Kalpit VeerwalJEE Main 2017, AIR 1

Mr. Kalpit Veerwal, the all India topper of JEE Main 2017, talks about how to prepare for thecoveted IITJEE. Read on:

JEE Main mainly requires decent speed, accuracy and problem-solving capacity. All youneed is CBSE level knowledge. Your first step should be to prepare well for the boardsand know each line of NCERT well.

Then you should focus on JEE Main when you are confident of each topic of NCERTlevel (JEE Main has a lot of focus on NCERT specially in Chemistry). Start by solvingprevious year papers to get an idea. Then go for objective questions (try getting a goodcoaching material because it’s better than books).

Start developing speed by solving full papers of 3 hours. Procure some test papers frominternet or friends or whatsoever. Then go for JEE Main. Try securing a good scoreto ensure an NIT (a good reading of NCERT + some objective practice is sufficient).

Books- past paper topic wise of AIEEE and JEE Main, P Bahadur Objective exercise 1, MCQby D. Mukherjee, R.D. Sharma Objective etc. I didn’t use these books much, but I guessthey are for JEE Main. Focus more on NCERT and coaching material for JEE Main.

22

Here he discusses his study habits in detail:

23

I attended all classes as a rule and listened attentively.

I followed a fixed sleeping and waking routine, and had at least 7 hours of sleep at night.

Keeping a diary with daily, weekly, monthly and long-term goals mentioned always helped.Also, short notes are a boon a few days before the exam.

I went home and read notes of what was taught in class. It helps in understanding thematerial a lot.

I discussed all my doubts with teachers during discussion. Even the simplest and stupidest.People sometimes find a hard time trying to believe my (little) achievements, because of the simple doubts I ask. But trust me, they lead to concept clarity. You have to be a littleself-centered to be at the top.

Books always give you an upper edge. People keep on solving problems and ignore thepower of theory. Problems will take you to 90%. The rest 10% comes when you read astandard textbook. I tried to solve tougher problems than what I was able to at that moment.

I don’t indulge in group discussions. It kills time and I don’t find it productive. I try solvingthings on my own.

There are few other points like avoiding non-productive activities, NOT listening to music/watching TV while studying, taking breaks but not too often, etc. Rock (Linkin Park) helpsin staying awake during late night studies though. Staying focused is very important.

Mr. Parth Sharma graduated in Computer Science from IIT Kanpur. Here is what he has to say:

Parth SharmaJEE Main 2014, AIR 4

Class 11: Just kept up with the homework (sometimes even missed that). Chilled out a lotwith my friends and had epic conversations with them during breaks and on the way backhome. Played Counter Strike occasionally and read a lot of books (both fiction and non-fiction).

On days when I skipped school, I usually woke up at around 7:30-8:00 am and studied till12:00 with a few breaks until I took a lunch break at 1 pm. After that I studied until I leftfor coaching (which was at 2 pm or 3:30 pm). After coming back from coaching, I had dinner,watched TV, surfed the internet and read books around 12 o’clock after which I slept. Onan average I studied about 5 hours daily.

In both years, I never managed to complete any extra book, except the relevant portionsof Loney, Irodov (very sloppily!) etc. I did some chapters of TMH for math but it was riddledwith mistakes, so I stopped solving it.

24

Then I started studying less number of hours again and at home with the same scheduleas before, Started hanging out with my friends and chilling out when I felt like it. Ranksimproved again (although never really got the 1st rank). I realized that my mental healthcomes first and I managed (although not perfectly) to stay motivated and happy duringthe last 6 months.

Source: Quora

If you compare the preparation strategies of the two toppers, you will realise that KalpitVeerwal represents a perfect example of what you call an ‘ideal’ student. On the otherhand, Parth Sharma appears more of a ‘regular’ but otherwise brilliant student. One canimmediately relate with him and his problems. If we talk about JEE, achievement level ofboth the toppers are very close, but there is a stark difference in their study techniques.There is a lesson to be learned here, that no matter what kind of student you are, hardwork pays off. Instead of counting the number of hours you devote, focus on the qualityaspect of preparing for JEE. Spend more time studying, instead of worrying or stressingabout it. As Parth Sharma rightly puts it, your ‘mental health comes first’ . If your mind isat peace, nothing can stop you from achieving your dreams.

’

25

Class 12: Started studying harder (approximately 7 hours) and initially got good resultsbut after a while my ranks began to drop, paradoxically. Realized I as burning myself outwith undue stress and spending more time worrying than actually studying. I was moreconcerned with the number of hours I studied rather than the actual studying. I alsomanaged a cut off from my friends and family as I started studying in my teacher’s office(I went there in the morning and returned after the class).


1. Begin Early

Begin your preparation sincerely from class 11. Two years of consistent study is sufficientto crack JEE and get a good rank. There are several advantages of beginning early:

The PCM concepts which you study in class 11 and class 12 are all connected with oneanother. If you cover the basics and the fundamentals in the beginning, it will helpyou understand the complex concepts in the later chapters without any difficulty.

It will boost your confidence as you understand your lessons better and tacklequestions with ease.

2. Schedule your Study PlanRemember that these two years of your life is equivalent to meditation. You must planyour time-table well and follow it religiously. Make a note of the chapters you havecovered and use the remaining time to prepare the rest of them. Prepare a strict timetablearound it. Remember, time management is very important in these two years and planningis the first step to success.

3. Mark your Calendar & remain Updated

4. Study Smart


Maintain a calendar for all important dates around JEE Main – application dates, edit detailswindow, admit card availability, online exam date, result declaration, counselling dates, etc.The idea is not to miss any deadline that would make you regret later. Additionally, keepchecking NTA’s official website for any updates, or changes regarding the exam, so youdon’t miss out on any critical information. Always remain updated about the JEE Main syllabus,exam pattern, eligibility, marking pattern, etc.

It is known for a fact that the JEE Main syllabus is huge! Moreover, the stiff competitiononly adds to the difficulties of a student preparing for it. Under such circumstances, smartstudy is very vital. Instead of learning those lengthy chapters, opt for concept-based learning.Start with NCERT and work upon building a strong foundation. Maintain separate notes forimportant formulae, equations, theorems, proofs, etc. Keep these notes handy for dailyrevision. Only a smart study plan will ensure success in JEE Main.

Tracking your mistakes is a crucial step in completing your preparation for a particular topic.Whenever you finish reading a concept, note down all the topics that you did notunderstand, grave errors or silly mistakes you made, etc. This will help you a lot in therevision phase. You will know how much you have improved upon your mistakes.

Solving previous year question papers is the most essential aspect of your preparationprocess. It gives you a fair idea of the types of questions you can expect in the actual exam.You will know the difficulty level of questions and be in a better position to analyse theextent of your preparation. For any student seriously considering a rank in 3 digits,he/she must solve JEE Main Question papers of the last 10 years.

7. Take Mock Tests in Real Exam Environment


JEE Main is now online and computer-based (No more pen and paper mode). While thismay be a new change for many, who says you can’t use it to your advantage?

Once you prepare a concept, take its concept test immediately to know how much youhave understood it.

Online tests give a question-wise analysis of your performance. These details help inanalysing your strengths, weaknesses, and areas which require improvement.

Practising mock tests improves your speed and accuracy. Since these are timed testswith a clock ticking on your screen, you constantly remain aware of the remainingtime and learn to finish these tests on time.

Solving mock tests gives you a feel of the real exam environment – same screen, markingpattern and difficulty level. This helps you get accustomed to all the aspects of taking anexam in the online mode.

8. Take a Break


Take Free Test

Besides the aforementioned advantages, some online tests also benchmark your performancewith other JEE aspirants and calculate your real time rank. myPAT, for instance, comparesyour performance against 700,000+ other students like you and helps you know whereyou stand. Take a free test now to know your current preparation level.

“All work and no play makes Jack a dull boy.” Little phrases that you learn as a child holdgood even after you grow up to become an adult. This holds completely true for JEEMain as well. With so much to learn, students often have the tendency to stretch theirstudy sessions. Running between tuition, school and home, they often have no time forrelaxation. But it is important to understand that giving yourself a short break in betweenyour hectic study schedule, only helps you concentrate better. Study well for a few hours,and then reward yourself with a well-deserved break. Use this time to relax, play a sport(which is not too exhausting), take a nap, etc.

Best Books for JEE Main 2021

Lots of books to study from?

Some suggested by teachers, others by toppers and the rest by your friends? myPAT expertsadvise you to prefer quality over quantity. Don’t study from 10 different books. Pick 1-2 goodones and read them thoroughly. To help you out, we have jotted down a list of importantbooks which you need for JEE Main.

Trigonometry and Geometryby S.L. Loney

33


Physics

JEE Physics is tougher as compared to Chemistry. However, if you prepare it well, Physicswill give you an edge over others.

Start with NCERT and work upon understanding the basics. From class 11th syllabus, the most important topics are mechanics, heat, thermodynamicsand gravitation.

Get your free body diagrams right and you will easily be able to solve every problem in mechanics.

From class 12th syllabus, the most important topics are electromagnetism, optics, currentelectricity, modern Physics and electronics.

Current electricity is the easiest out of them and scoring too. Prepare it well.

For chapters like EM waves, semiconductors, etc. NCERT is sufficient.

Therma Physics requires a grip on formulas. Memorise them as they will come handy in calculations.

Be very careful with sign conventions, lens and mirror formulas in Optics. The questions requirea strong foundation and clarity in concepts. Draw ray diagrams. That’ll help.

For preparation, start with NCERT exercises followed by HC Verma. Solve every question at theend of every chapter in these books.

Once you’re done with them, solve the problems in IE Irodov and Resnick, Walker, Halliday.

35


Chemistry

Often considered as the easiest of the three subjects, JEE Main Chemistry can be easilynailed by a thorough study of NCERT Chemistry (Part 1 and 2).

Chemistry syllabus can be divided into physical, organic and inorganic Chemistry.

Physical chemistry is the simplest section. Know its formulae well and learn to apply them.

While practising questions in physical chemistry, learn to do multiplications and divisionsquickly. This will save your time during exam. You will find application-based questions which will be easy to solve if you have the formulason your fingertips.

For organic Chemistry, you must memorise important equations to score well.

Focus on understanding the mechanism of reactions.

Inorganic is completely theory-based and all about mugging up (after understanding).

Understand the trends for elements and their compounds.

Practise the reactions. Write them repeatedly so that they are etched in your mind.

Read NCERT in and out. Don’t skip a single line of it – that’s the trick to prepare for Chemistry.

If you put in a little effort, you can easily score 90+ out of 120 in Chemistry. 36


Mathematics

JEE Mathematics is considered as the toughest out of the three sections and you need a lot ofproblem solving to excel there.

Calculus, undoubtedly, has the maximum weightage in JEE Main question paper. You needto memorise lots of formulae and tricks while practising. Even an average student can scorewell in these questions. Coordinate and Circles are also very important. Even for these chapters, you are supposedto remember lots of formulae and know when to apply which one. 3D Geometry, Vector and Integrals are highly scoring and primarily calculation-based. Practisethese chapters diligently to score full marks. Stats, Probability and PnC get the least weightage and are arguably the toughest portions.You need a good understanding of the concepts and substantial amount of practise tocrack the questions of these chapters. The best books for JEE Main Math are NCERT, RD Sharma and Cengage.

37

The D-Day Strategy

JEE Main paper has 75 questions – 25 from Physics, Chemistry and Mathematics each. Here are somepointers that IITians have shared about their exam day experience:

Before you enter the exam hall, know this – you will not be able to solve all the questions,neither will be any other person be. And it is perfectly OKAY! You have 180 minutes to complete the paper with 25 questions in each subject. But donot make the mistake of assuming that you have 1 hour for each subject. Chemistryis expected to be completed in 35-40 minutes. You will require remaining time intougher sections, that is, Physics and Math.

80 minutes is enough for solving the Math section, which leaves you with an hour forPhysics.

While solving questions, first opt the ones which are easy. Since each question hasequal marks, do not miss out on any question which you can solve. Next, go throughthe entire paper to spot moderate questions. Tackle them and move to the toughones only at last.

JEE Main has negative marking for incorrect answers. So, avoid guessing answers. A fewcalculated guesses are okay. But do not go overboard with it as even 1 mark can costyou hundreds of ranks in JEE.

39

The D-Day Strategy

Do not freak out if you are unable to solve some questions. Additionally, do not spendtoo much time on one question. Move on. You can come back to it later. Once you read a question, go through its options before you start solving it. You mayoften be able to find its answer simply by eliminating the incorrect options. This willsave you the time and effort of solving it. While you are at it, do not rush into solving questions. While we won’t ask you to betoo generous with your time, but simply rushing will end up in a lot of silly mistakes.So, relax. There are negative marks. Concentrate and be accurate with your solutions. Remember to use the tricks and shortcuts that you have used during preparation.
