How to prepare for JEE in 3 months? After years of preparing yourself for the toughest exam known to Indian students, you suddenly find that your exams are just around the corner. Howsoever you have prepared for the JEE all this long, the last three months can still be game-changing. 

The most important thing you need to acquire in the next 3 months is confidence. The more confident you will feel while entering the exam hall, the better will be your approach towards the questions. It's very similar to a batsman coming on the cricket pitch, if he is not confident of playing his shots, he will always be in a dilemma as to which shot to play on a ball. To gain the required confidence, you should know how to solve problems of all possible types. The best strategy for this is solving one particular book multiple times before moving on to practice questions from multiple books on the same topic. This way you know how to solve problems of all types. 

In this last leg of your preparation schedule, try and divide the syllabus according to its weightage and revise what you have studied earlier. Train yourself in the easier portions first. Also, remember that you will be preparing for your school final exams during this time. Divide your time between JEE prep and Boards prep judiciously. While preparing for JEE, you would automatically be preparing for class XII Physics, Chemistry and Maths. You will still have to budget some time for preparing other subjects such as English and Computers. While board marks are not the deciding factor for JEE, it is still required to score greater than 75% marks to appear in JEE and it is important to get good marks in all the subjects of board exam for the purpose of shortlisting for placement later on in life. 

Physics

A good grasp of concepts is where you start in Physics. Ask yourself how thorough you are with concepts. Unless you learn the concept very well, you will not be in a position to tackle all the questions from the given topic. While practicing a question, first start with a diagram so the problem is clear to you. Mark all the forces acting on the body and imagine the possible motion of body so that you can conceptualize the problem. Once forces are clear to you, you just have to break the vectors in their components and solve each direction independently. This holds true for mechanics and electrodynamics. For thermodynamics and Optics, you don’t need the diagram as much. 

 The various topics that are important from the exam perspective are:

  • Kinematics
  • Newton’s Laws of motion
  • Simple Harmonic Motion (SHM) and Oscillations
  • Heat and Thermodynamics
  • Electrostatics & Current Electricity
  • Modern Physics and Radioactive Decay

Have an eye on your time management. 

Best Physics books for JEE 2020

  • NCERT Physics Textbook (classes 11 and 12)
  • HC Verma: Concepts of Physics (Part I & Part II) 
  • Understanding Physics Series (Set of 5 Books) by D. C. Pandey (Arihant Publications)

Chemistry

This is a subject that needs a lot of information memorization. But, the great thing about Chemistry is that you can score a lot. For Physical chemistry, the approach has to be very similar to how you would approach Physics, clearing the concepts and practicing problems of all types. For Inorganic Chemistry, you need to prepare very concise notes which you can revise within 1-2 days every time, so that it is revised at least 10-15 times in the last 3 months.Without revising multiple times, you won’t be able to recall all the steps during exam. For Organic Chemistry, the approach needed is a mix of Physics and Inorganic Chemistry. You need to be clear with concepts and at the same time, you need to memorize the named reactions and all conditions of reaction.

The chapters that are important from the perspective of JEE exam are:

  • Mole Concept
  • Chemical kinetics & Equilibrium
  • Named Reactions in Organic Chemistry
  • Electrophilic aromatic substitution reaction of Benzene and its derivatives
  • Coordination compounds
  • Metallurgy

While chemistry prep does involve a lot of memorization, just rote learning wouldn’t help you if you don’t understand the underlying concepts. Figure out the complete mechanism behind reactions. And before you know it, learning comes naturally. 

Organic chemistry does take time. So, use your exam time wisely. Save these questions for the last leg and complete physical and inorganic chemistry parts first. 

Best Chemistry books for JEE 2019

  • NCERT
  • Organic chemistry (O. P. Tandon) 
  • Inorganic Chemistry (J. D. Lee)
  • Physical Chemistry (R.C. Mukerjee)

 

Mathematics

Mathematics is all about building a solid foundation. The last three months would involve honing accuracy, time management, and optimization. So, learn those shortcuts and practice enough to apply these shortcuts. Best way to spend your time for Maths would be to practice previous year question papers. The more confident you are about all parts of the syllabus, the better will be your approach. The math part of JEE is highly unpredictable. But it would be safe to say that the topics that have been largely important are:

  • Calculus
  • Vectors & 3D
  • Permutations & Combinations and Probability
  • Conic Sections

Wherever you can, substitute the option values to figure out what works and what doesn’t. In coordinate geometry, make rough graphs and plot points given in the options to figure out what could be the answer. 

Best Mathematics Books for JEE 2019

  • NCERT mathematics
  • Mathematics for JEE (TMH)
  • IIT Mathematics by ML Khanna

While all the points mentioned in the article will benefit you but most importantly, you have to relax and not be too hard on yourself. Keep a calm mind, do not take stress and approach the problems with a cool mind. Whatever happens, at the end of day it is just an exam. Do not take so much pressure that it starts affecting your performance on the exam day.
