Guide for improving weaker topic during JEE Preparation

Here is a guest post  by Zeel Shah ( IIT BOMBAY, AIR 1731, JEE ADVANCED 2019) 

 A must-read for everyone.

“Suppose you have your JEE Advance paper tomorrow, which subject you are confident to score the most? Are you sure that you can attempt ~70% paper correctly of the Advance level? “These types of questions raised by the director of my institute before two months of the final exam.

This is to show you that your end goal is to score high in a given time with pressure in the exam. So subject fetching more marks per time is strongest, not the one’s problems you enjoy solving.

So, now you have decided which is your weak subject, here are my suggestions :

Analyze past trends and find preference order of chapters. In JEE Advanced, there are inter-topics multi-layered questions but just get a superficial overview and figure our what chapters have more weightage.

Your first focus should be on top topics as again the main goal is to be able to attempt 70%. It is pointless to study 70 pages of salt analysis whose even one question appearing in the paper is uncertain. especially when your basic and important parts are weak.

You need to spend time with that chapter. You need to try different methods and check if that is helping. Keep tracking progress through timed question solving and improving preparation methods. There is no specific way for every chapter and subject. It depends on the individual also.

You may

• read theory,
• solve problems from the module,
• note down important points and formula on one paper and revise them multiple times,
• attempt past year asked methods,
• Note down imp formulas and types of questions derived from them
• read NCERT,
• listen to revision videos on youtube. ( don’t overdo this )

Point is you need to figure out what methods to use for a particular chapter by trying them, tracking them and spending time with the chapter.

weakness is in your mind, a subject is just a subject :p

Here is  my own experience of improving my weak topic coordinate geometry .

They started teaching circles in the 11th. It was going good, I was following what was taught in the class, then started parabola, its properties, conditions for tangency, director circle, and whatnot.

Still was able to solve basic problems, but things started to get messy, couldn’t click the right method, and couldn't solve a problem in the given duration. After ellipse, hyperbola things started to become dirtier. what condition when vertical ellipse, how to solve problems of rectangular hyperbola- made me confused.

Now I had two options:

• rant about the topic and leave such high weighted topic
• or try whatever I can till I have no regret when I go to give the exam.

I was already reading notes and questions solved in class repeatedly, I started trying different things :

• I spent more time-solving problems,
• After I have solved them once ( solving doubts from faculty, friends ) I made an extra copy and noted down all questions and answers carefully.
• I even noted what part of the question statement gives hint to do a particular method.

Now, my original plan was to revise this written solution many times, but I couldn’t revise much as other things packed me.

Now fast forward to 12th, I was still not confident about chapters. One reason I figure out was there were too many formulas and conditions for every conics.

I sat down, searched revision video for circles, and found a video of COACHengg. ( You check on the youtube ) I wrote all points covered in that video on one page. Did the same for all other conics.

After revising several times, I realize this is so much information to remember and I won’t be able to recall it in exam pressure.

I removed extra information and left about five important things per conic to remember. So, I deliberately left portions and focused on solving past papers at the end.

Did all these help me in improving the score ?

I don’t know, but I was satisfied before the day of JEE that I have tried.

The point I would like to tell JEE Aspirants that :

We even didn’t know what is the right method, we tried and saw if that was helping. We found out methods to revise and remember formulas that worked for us. Only you can figure out what is working for you, keep trying.

P.S.: You can’t ricks to leave this chapter. -Baburao :p

Keep Smiling,

Good Luck

USEFUL TIPS TO FIGHT PROCRASTINATION: NOW OR NEVER

USEFUL TIPS TO FIGHT PROCRASTINATION : NOW OR NEVER

What is procrastination? – Procrastination can hit anyone anytime! For those who aren’t well versed with what procrastination means, let us try to get it straight. Procrastination is the action of delaying or postponing something often because it is boring or you’re being too lazy. Now students might procrastinate while preparing for entrance exams but doing so will only take them away from their target. So, students need to follow these simple yet effective tips to beat procrastination.

How to beat procrastination

here avail the effective tips to overcome procrastination. Student needs to follow these Sample tips.

1. Make a commitment: Students generally overburden themselves with too many things at once which results in procrastination. Rather pick just one thing and stick to it until you complete it. Follow the same rule while completing a topic. Set a schedule and follow it religiously. You need to make a commitment to yourself and accomplish the task within the stipulated time. Establish specific deadlines for the completion of tasks. Delaying or postponing things will only make things worse!
2. Focus is the key: Do not focus on short-term gains. Keep reminding yourself of the long-term results. Repeat your aim daily as to why you had wanted to prepare for the exam. Visualising the end result will help you focus on your target. Analyse the factors that lead to procrastination and work on those particular sections for improvement. If you aren’t able to focus properly, then I recommend you to start meditating. Meditation has/can work wonders & will surely help you focus on studies in a more efficient manner. Get rid of distractions and by this we mean get rid of social media and those addictive gaming apps which will lose your focus.
3. Reward yourself: Before beginning any task all you need to do is, set a reward that you’ll give yourself. According to a research the human brain responds to reward stimulus! Find yourself an accountability partner, someone to whom you can report post the completion of a task. If you are fond of reading you may get yourself a book that you’d longed to read or if you love food then you should probably find yourself at a fancy restaurant once you have achieved your set target.
4. Make the task interesting: Boredom can often lead to procrastination. So, try relating the concepts to practical situations. This way not only the syllabus will seem easy, but the topics will also become even more interesting to grasp. 
5. Divide your task: If any chapter  seems to be too long then divide it into topics. Chunking big tasks into small sections will ease your task. Start taking actions on these little chunks. Use the golden 5-minute rule, i.e. whenever you face any complex task then just ask yourself about what can be done in a mere 5 minutes to bring your closer to your target. And you’re done. For a better understanding begin with topics that are important and difficult. Later, keep revising those portions until you become become pro in the subject.

Hope the above tips help you beat procrastination. Do let me know your views in the comment section below.

ELECTROMAGNETISM FOR JEE MAINS AND ADVANCED

ELECTROMAGNETISM FOR

 JEE MAINS AND ADVANCED 

Electromagnetism forms the major part of the class 12th syllabus and is one of the highly weighted sections for JEE Physics. This entire module requires a lot of practice, intuition and problem solving skills. The mechanics portion learnt in class 11th acts as tool to solve the problems of electromagnetism (Yes! You are going to need it!  Quite a lot from sections: energy conservation, momentum conservation and Newton’s laws of motion).
Let’s go chapter wise to make things simpler:

• Electrostatics: Electrostatics begins with Coulomb’s law, principle of superposition and then goes on to the concept of electric field, electrostatic potential and other ideas that form the basis of electromagnetism. These are the fundamental concepts and the students are advised to get a thorough understanding of these topics. Sufficient practice is required for all of these topics. In JEE, simple questions are asked from this topic which can be cracked easily, if one has refined concepts. An important portion of electrostatics is the concept of “conductors in electrostatics”. Most questions in electrostatics are based on the properties of conductors under electrostatic condition. So, it is recommended that students should practice ample of questions from this topic. Another extremely important idea is the idea of electrostatic flux and Gauss’s law. Both of these ideas are highly important and if one can correlate them with other topics, they can be very useful to solve completely unrelated problems. Usually, there is always a question in JEE which ultimately involves calculation of flux of a charge through some or the other surface.

• Capacitors: This chapter is another simple but important part of JEE syllabus. It is basically the application part of electrostatics. Those who have covered electrostatics well would find this chapter a cakewalk. Some new concepts taught in this chapter are very interesting and easy to understand. This chapter is important from the point of view of Olympiads as well. The idea of dielectrics is also introduced with this chapter and a number of questions are asked in JEE which require you to calculate energy stored in capacitor / electric field by capacitor, etc. – all involving concept of dielectrics. In fact, an entire question in INPhO 2013 was based on a capacitor with a dielectric whose dielectric constant varied as a function of position.

• Current electricity: Ohm’s law and Kirchoff’s law form the key framework of this chapter. It’s one of the easiest chapters in JEE syllabus and it takes only a little effort to master it. However, the chapter has fairly good weightage in JEE and so it is recommended that students practice a large number of questions from this chapter so as to avoid silly mistakes in the exam. RC circuits are very important from the point of JEE. One should keep the “mechanical analogy” in mind while solving the problems of RC circuits. Sometimes, a tough RC circuit problem can be solved within a minute if one is able to figure the appropriate mechanical analogy. Another important concept is “heating effect of electric current”. This concept combined with the ideas of thermodynamics may be used to form some of the best mind bending questions.

• Magnetism: This chapter involves numerous applications of the mechanics portion learnt in class 11th. Good questions are framed under the concept of a particle in an electric as well as magnetic field. And one should be thorough with various concepts of mechanics to be able to solve the problems, particularly, basic kinematics, work energy theorem (+ the idea that magnetic field doesn’t do any work), law of conservation of linear momentum, etc. Most questions are asked from calculation of magnetic field in various cases. Another important “centre” of questions is – Magnetic moment. It has been observed that there are a few questions in JEE from magnetic moment, every year. So, it is recommended that students practice enough questions involving calculation of magnetic moment and related applications like – basic idea of magnetic materials and the explanation using the concept of magnetic moment. A loop in a uniform magnetic field is also an important topic of discussion. Several questions are asked from this. Some good problems are also derived from the concept of “moving coil galvanometer”. So, boot yourselves up and get ready to see a few new questions in JEE from magnetism as well. 

To conclude, Electromagnetism forms a big portion of JEE syllabus and if practiced properly, it may help you change your rank completely. But, at the same time, Electromagnetism needs a lot of practice and patience to master. Initially, one may find it boring/ difficult to understand for whatever reasons, but it becomes very easy (and fun too!) if ample no. of questions are practiced from the prescribed textbooks/ study material.

10 VEDIC MATHS TRICKS TO MAKE YOUR CALCULATION FASTER

10 VEDIC MATHS TRICKS TO MAKE YOUR CALCULATION FASTER

 Tired of doing calculations 

Ever lost marks due to silly mistakes??

Have you spent a looooooooong time calculating answer for a particular problem and still got it wrong.

Don't worry with these tricks your calculation will become easier

1. How to square a number whose last digit is 5

This vedic maths formula is pretty simple by which you can square any 2-digit number which has 5 in its one’s place.

First, multiply the 1st digit on the left-hand side with 1 and then, write 25 at the end.

That’s trick 1 for you. You still didn’t get it. See the example below: –

For example: (75) ² =?

Step 1:75 x 75 = …….25 (at the end)

Step 2:7x (7+1) = 7 x 8 = 56

Therefore, the answer is 5625.

2. Multiplication of a number with 5

Memorizing 5 table is every easy. But as the smaller numbers turn to larger numbers, calculation turns complex. This vedic maths technique helps you to solve this problem.

Here, you have to take any number and divide it by 2. If your result is a whole number, then add 0 (zero digit) at the end of the number. If it is not a whole number, then add 5 at the end and ignore whatever remainder you have got.

For example: 8426 x 5 =?

Step 1: 8426 / 2 = 4213

Step 2: It is a whole number, so add 0

The answer will be 8426 x 5 = 42130

Let’s try another: 7337 x 5

Step 1:3773 / 2 = 3668.5

Step 2: This is a fractional number, so we will ignore remainder and add 5 at the end.

The answer will be 7337 x 5 = 36685

3. How to subtract a number from 1000, 10000, 100000 and so on.

This maths technique is very useful when you want accurate subtracted results from 1000, 10000, 100000 and so on……

There is only one formula – Subtract all the digits from 9 and last digit from 10.

For example: 1000 – 876 =?

We simply subtract each figure in 876 from 9 and the last figure from 10.

Step 1. 9 – 8 = 1

Step 2. 9 – 7 = 2

Step 3. 10 – 6 = 4

So, the answer is 1000 – 473 = 124

4. How to Multiply any 2-digit numbers between 11 to 19

This trick is of great help if you are just like me and cannot remember the tables after 10. Once practiced for adequate amount of times, you can calculate the results very fast. There are in total 4 steps to solve through this type of trick.

Step 1:  Add the unit digit of smaller number to the larger number.

Step 2: Multiply the sum result by 10.

Step 3: Multiply both number’s unit digit.

Step 4: Add both the numbers (which were involved in step 1 & step 2).

For example: Take 2 numbers like 12 and 15.

Step 1. 15 + 2 =17

Step 2. 17*10 = 170.

Step 3. 2*5 = 10

Step 4. Add the two numbers, 170+10 and the answer is 18

5. Division of a large number by 5

This technique quickly gives the answer after division of any large number by 5. There are only two steps which you need to follow. First, being multiplication of number by 2 and second being removal of digit after decimal point.

For example: 415 / 5 =?

Step 1. 415 * 2 = 207.5
Step 2. Move the decimal: 207.5 or just 207

6. How to Multiply any two-digit number with 11

Using this mental math trick, multiplication can be done swiftly.

To multiply 45 and 11, let us imagine that there is a gap between 45
Step 1: Put an imaginary space in between: 45*11= 4_5
Step 2:  Just add 4 and 5 and put the result in the imaginary space
So, the answer is: 45 * 11 = 495

Let’s try another number….

36 * 11 = 3 (3+6) 9 = 396

7. Multiplication of any large number by 12

In order to multiply any no. by 12 we need to just double the last digit of the number and then, double each digit and add it to its neighboring number.

For example: 3243 * 12 =?
Let’s break it into simple steps:
Step 1. 3243 * 12 = _____6 (Double of Last Digit 3= 6 )
Step 2. 3243 * 12 = ____16 (Now Double 4= 8, and add it to 3, 8+3=11, 1 will get carry over)
Step 3. 3243 * 12=  ___916 (Now Double 2=4, and add it to 4 with carry, 4+4+1=9)
Step 4. 3243* 12=   _8916 (Now Double 3=6, and add it to 2, 6+2=8)
Step 5. 3243 * 12=   38916

So your final answer of 3243 * 12 = 38916

8. Multiplication of any 3-digit numbers

Take any two numbers like 204 and 206
Step 1. Now subtract the number at unit place.
204-4=200
206-6=200
Step 2. Now select any no. and add the unit digit of another no.
204+6=210
Step 3. Now multiply, 210×200 = 42000
Step 4. Now multiply the unit digits of both numbers, 4×6=24
Step 5. Add, 42000+24 = 42024

The product of the numbers 204 and 206 is 42024

9. How to calculate square of any number

Calculating squares can be very easy if you are doing it using Vedic maths.

Step 1. Choose a base nearer to the no. whose sq. is to be found.

Step 2. Find the difference of the no. from its base.

Step 3. Add the difference with the no.

Step 4. Multiply the result with the base.

Step 5. Add the product of the sq. of the difference with the result of the above point.

Let’s take an example to understand this: (88) ² =? 

Step 1. Choose 100 as base

Step 2. Difference =88-100 = -12

Step 3. Number + difference = 99 + (-12) = 87

Step 4. Multiplying result with base = 87*100 = 8700

Step 5. Adding result with square of difference= 8700 + (-12)² = 8844

10. Multiplication of any number by 9

( I know you guys must be like Whhaaaaat!! We knew this before, but this is very quick when it comes to big numbers)

A COMPLETE GUIDE FOR GUESSING CORRECT ANSWER IN MCQ

 Tips to Become the master of MCQs in IIT JEE: Guessing Your Way to the IITs!

• 
  

As we know, JEE is the toughest entrance test in India. But how many of you know the tricks to mark correct answers for MCQs in JEE Main and JEE Advanced? I know a few.

In JEE, all questions are objective. The Multiple Choice Questions (MCQs) has four answers, out of which sometimes only one and at times two options are correct. Students need to circle the correct option for every question and earn marks.

It is usually seen that candidates consider objective questions easy as compared to subjective. Despite of the wide spread liking towards MCQs and IIT JEE paper pattern, multiple choice questions could be difficult to tackle. At times, the choices may appear similar and therefore you might get confused. In order to answer the questions correctly, students need to have deeper insight of every topic in the syllabus. Students can use the below mentioned tricks for both online and offline exams:

Be Calm Candidates should make sure they are stress free and calm before writing IIT JEE test. Since, due to tension you may lose concentration and might mark a wrong answer. Understand the question Identify the important part of the question and apply your logic. Understand what the question is before marking the answer. Tick the answer only when you are sure. Choosing correct answer is really important, since every wrong answer might result in deduction of marks (due to negative marking in the exam).

Example:

From a tower of height H, a particle is thrown vertically upwards with a speed u. The time taken by the particle, to hit the ground, is n times that taken by it to reach the highest point of its path. The relation between H, u and n is?

 (IIT-JEE Mains 2014)

(a) 2gH=n2u2   

 (b) gH = (n-2)2u2

(c)  2gH =nu2(n-2)

   (d) gH = (n-2)u2

Immediately, identity the topic and apply concept related to it (Projectile motion in this case). Make the diagrams for better understanding to make sure you land up to the right answer choice.

Check the Dimensions This technique is very handy in Physics paper, where we can filter options by looking at their dimension. Let say, we are to find the speed, then we can safely filter out options whose dimension does not equals m/sec. Believe me, it will save a lot of your time.

Don't be in hurry during JEE Giving the right answer is very crucial in IIT JEE therefore mark the answer carefully. Don't guess the answer too soon! Take some time to think and make necessary calculations. Stop and read the question and options carefully.

Method of Assumption This is another important method. In some of the questions, some unknown quantities will be given. Here, we assign some values to these quantities without changing the conditions given. This is almost similar to the method of substitution.

Example: If a(n) denotes the nth term in an Arithmetic Progression. Then

1/a(1)a(2) +1/a(2)a(3) + 1/a(n - 1) * a(n) =

(a) n-1/a (1) a (n) 

 (b) n/a(1)a(n+1)

(c)n-2/a(1)a(n-1) 

  (d) n/a(1)a(n)

Sol: Take a simple AP=1, 2, 3,4. let us take n=3.

Therefore our questions comes to be:1/1*2 +1/2*3 =4/6 =2/3= n-1/a(1)a(n).

Hence the correct option is (a).

Choose technically correct option and Generalize Questions It is often seen that people tend to ignore options like all of the above and none of the above thinking such options are never correct. In reality, these options tend to be right more often.  Also, don't jump into any option abruptly.

Questions like ax+by+cz= k, can we solved by using general values like a=1, b=1, c=1 to see if it solves our purpose.

Do a little guess work Even though guess work is not always the best practice, it might work at times. If you are not sure of an answer, make a guess! Delete some options which you think are in correct and try to relate the leftovers with the questions to check what answer you get. Remember, guess work is not always beneficial. So try to avoid it! 

Example:When a rubber-band is stretched by a distance x, it exerts a restoring force of magnitude F = ax + bx2 where a and b are constants. The work done in stretching the unstretched rubber-band by L is:

(a) aL2 + bL3 

 (b) (aL2 +  bL3) / 2

(c)  aL2 / 2 +  bL3 / 3 

 (d) aL2/ 4 +  bL3 / 6

As we can observe from the question that a and b are with different powers of x and hence there the answer is most unlikely to have same coefficients. Hence options a and b can be eliminated and even with a little amount of knowledge, we can chose among c and d.

Don't change your answer Avoid changing your answers frequently. Generally, first answer is always correct. Regularly changing the answer might prove wrong at the end. This also leads to confusion. Therefore, stick to one answer regularly.

Reverse engineering Reverse engineering, taking step backward. Instead of solving complete equation, we just apply value in the equation to see if it solves it.

Example: The straight line 2X + Y = 5 , for different values of x and y passes through the fixed point

(a) (2,9)

  (b) (2, -9)

(c ) (-2,-9)

 (d ) (-2, -9)

Move on Despite of so many attempts, if you are not getting the right answer, switch to the next question. Sticking to just one question will waste your time. Solve other questions and return to this one once you have done all the rest. You can spend the remaining few minutes in solving this question. Later on once you have done filtering, dimension check, you can apply law of probability (as per option 1) and choose one option. Remember, probability is now on your side.

Discard highest and lowest outliers Outliers mean choices having extreme values. If your test paper has any question which have answers in numerical values, discard the extremes. In 60% cases, the highest and lowest values are not right. So, be very careful while choosing the answer. They have high probability of being wrong. So candidates can safely stay away from this unfamiliar zone.

Example: 

Let A, B, C be three sets of complex number as defined below:The number of elements in the set A intersection B intersection C is

(a) 0 

(b) 1

(c)2  

(d) 4

Here the answer is 1. This is not generalized rule but again applicable at many places.

Choose one among the two options If you have already checked out two incorrect answers, choose one out of the remaining options. You can use the first point to select the correct answer.

Attempt the no-negative marking questions At times, there are questions like match the following in the IIT JEE test. These questions don't carry negative marking therefore you are free to take chance. You should never leave such questions un-attempted. You should read and know the marking scheme correctly to attempt every question and earn marks. Usually exams marking pattern is +4 for each correct answers and -1 for each negative. And, assuming all options have an equal probability of being correct, student can at the leave have a minimum score of 0.25*n out of n questions (0.25 n *4  0.75n*1) by choosing only 1 option. In case, there is no negative marking, you can score 1*n. Hence, never leave any question unanswered if there is no negative marking.

If we go via topics, we can summarize the following:

Memorize easiest topics to get good marks

1)Algebra can be made easier if you have the ability to picture functions as graphs and are good at applying vertical and horizontal origin shifts carefully as zeroes of functions and other specific values can be done in much less time using these techniques.

2)  Differential calculus again relates well to roots of equations, especially if you use the Rolle’s and Lagrange’s theorems.

3)Complex numbers is very important chapter for JEE. It can be used to solve questions in co-ordinate geometry too. Trigonometric questions require applications of De Moivre’s theorem.  Every year, two to three problems (of purely complex number) are asked. Hence mastering complex numbers, vectors, 3-D and Definite integral must be on top priority.

4) Permutation-Combination and Probability is another very important topic in algebra. You need to be thorough with the basics of Bayes theorem, derangements and various ways of distribution, taking care of cases where objects are identical and when they are not.

5)Matrices can be related to equations, hence a 3×3 matrix can actually be visualised as being three-planed in 3D geometry. Determinants have some very nice properties, for instance, the ability to break them into two using a common summand from a row/ column, which should be made use of in tougher questions.

6) Integral calculus can be simplified using tricks and keeping in mind some basic varieties of integrable functions. Remembering the properties and applying them wisely saves lot of time.

7)Coordinate geometry requires a good working knowledge of the parametric forms of various conic sections and an ability to convert the other, tougher ones to these basic forms and then interpret the solutions accordingly.

Finally the only one way to do well in Mathematics is to practice problems keeping in mind the pattern of questions in the previous years’ JEE papers. Conceptual clarity, application skills and awareness to the prescribed syllabus should be the main focus. Practice the most relevant numerical daily to develop speed. Pay special attention to the topics like Mole concept, Chemical Equilibrium and Electrochemistry.

8)  Take a careful and patient approach for Organic Chemistry giving particular attention to the topics like Stereochemistry, GOC (General Organic Chemistry) and Functional Group Analysis.

9)  In Inorganic chemistry, most of the questions which are asked are really conceptual, concerned with structures, processes and applications and are very direct.

10) Special attention is a must for the topics like Chemical Bonding and Coordination Chemistry.

11)  Mechanics is one topic in Physics that is considered less scoring by most experts. However to add to the dilemma, this is also the topic that forms the major portion of the JEE (Advanced) in terms of marks. So this topic cannot be neglected.

12)  Modern Physics with its atoms, nuclei and radiations are some of the topics, which cannot be ignored during IIT JEE Test. In fact, these topics will help you earn about 20-25 marks in the exam. Also, it requires not more than a couple of days to understand this topic. So, memorize easiest topics to score well in the test.

13)  Kinematics and Particle dynamics are very important topics of Mechanics that make regular appearance in the JEE papers.

14)  Thermodynamics is important from the terms of both Physics and Chemistry so concentrate on that as well.

15)  One must also try to concentrate on other scoring topics to ensure a better performance, for example Optics, Electricity and Magnetism, etc.

Note: It is wise to cover Wave Optics first in ‘Optics’ topic. The reason is that the portion is smaller compared to Ray Optics and thus, quick to cover.

OTHER KEY GENERAL POINTS

• Stay focused and maintain a positive attitude.
• Develop speed. Refer to reputed mock-test series to build a winning exam temperament. Solve the past year’s IIT-JEE papers. Focus on your weak areas and improve upon your concepts.
• Practice of JEE level questions is necessary as it improves your reasoning and analytical ability.
• Remember it is quality of time spent and not the quantity alone that matters. Take short breaks of five to 10 minutes every one to two hours of serious study. It is important to relax. Practice meditation to develop inner calm, poise, confidence and power of concentration.
• Don’t overstress yourself. Five to six hours of sleep every night is a must, especially three to four days before the main exam to keep you physically and mentally fit. While short naps may help to regain freshness, avoid over-sleeping during the day.

If you find the paper tough, don’t be nervous. It is the relative performance that counts. So put your best analytical mind to work, and believe in your preparation. Good luck!
