How to prepare for JEE Mains in 2 months?

With the JEE Main exam approaching way too fast and with the very little, but crucial time left in hand, it becomes very important for an aspirant to plan things out. An aspirant needs to manage XII boards along with the revision of JEE, which becomes a major factor in the determination of their JEE Main rank. It is essential to manage the time meticulously in these days. Every step taken will determine their performance in the exam.

To start with, the dilemma that every aspirant face during these months is – the board exams. The fact that boards are given a weightage of 40% is tempting for an individual and they devote most part of their time towards the boards, which can prove to be a very dangerous thing. Even though it’s a completely agreeable fact that NCERT books are like the bible for those appearing for JEE Main, it doesn’t imply that mugging up the syllabus would get you an outstanding AIR. The syllabus may look similar but the pattern and level of questions differ in some way or another. The truth is, most questions that JEE asks are logical, where an individual has to apply every concept, to reach a solution. So adequate time must be given towards problem-solving for JEE besides the boards.

Keeping in mind that some topics are more important than others. JEE Main Exam covers 40 % of the syllabus from 11th standard and 60 % syllabus from the 12th standard approximately. The topic wise weightage of each subject for JEE Main is given below.

S.No. Chemistry  Physics Mathematics
Topics Weightage Topics Weightage Topics Weightage
1. Organic Chemistry 34 % Mechanics 25% Differential Calculus 15.20%
2. Inorganic Chemistry 30 % Electro Dynamics 22.58% Probability 7.26%
3. Physical Chemistry 36 % Heat & Thermodynamics 12.90% Integral Calculus 16.94%
4. Modern Physics 18.55% Matrix Determinants 11.29%
5. Optics 14.52% Coordinate Geometry 14.52%
6. SHM & Waves 6.45% Trigonometry 8.06%


The JEE Main Paper Pattern

If you want to succeed at this first step, you need to understand the right direction. So, we suggest you to have a complete review on JEE Mains 2018 Exam Pattern. Starting preparation without correct knowledge is severe wastage of time.

JEE Mains Exam is conducted in two papers –

Paper 1:

  •  The Paper 1 is conducted for Engineering Aspirants.
  •  3 Hours’ Time Duration to Solve the Objective Type Questions from Physics, Mathematics & JEE Chemistry.
  •  4 marks awarded for each correct answer and 1 mark is deducted for each wrong attempt.
  •  The exam is conducted in both Offline & Online mode.

Paper 2:

  •  JEE Main Paper 2 is conducted for Architecture Students.
  •  3 Hours’ Time Duration to Solve the questions from Mathematics, Aptitude Test & Drawing Test.
  •  Marking Scheme is same as Paper 1. The only difference is that in Drawing Exam, negative marking will not be applied.
  •  The Exam is conducted in offline mode only.

Subject wise strategy for JEE Mains and JEE Advance


Chemistry is the easiest and the most scoring part of JEE Mains and Advanced Paper. You should be having a great hold on Chemistry keeping in mind the situation you are in. Honestly, this is the subject that could still fetch you about 90+ (out of 120), in JEE if studied properly and with full dedication!! Chemistry could be divided into 3 parts,

– Physical Chemistry

This is the easiest part of all of the JEE syllabus. Go through all the chapters, studying each and every part and practicing lots of questions. You would need to memorize the formulas, have a good hold on a few concepts and should be able to do a little multiplication, division etc. Most of the question of this section are application based and require the memorization of formulas and a little bit calculation.

 Organic Chemistry

This again is also a very scoring section and needs to be understood well. You should know all the Reactions well, how they proceed and most importantly, the mechanism they follow. Most of the questions in JEE Advanced test how well you understood the mechanism of the reaction.

-Inorganic Chemistry

If you are good at mugging up which most of us are, this is a section which could surely fetch you 100% score. Inorganic chemistry requires a good amount of time to read and memorize each and every aspect of whole bunch of reactions. You would need to put in a lot of time in this section and put it again and again to master Inorganic Chemistry and if done with full dedication, it would surely throw back a great result.

Go through your NCERT thoroughly for Chemistry. NCERT is like a Bible for Chemistry. Read each and every line of NCERT by heart and understand every bit of it. Chemistry is a very-very scoring section of all three, and one should never Bluff with it.

Important Chapters: Mole Concept, Equilibrium, Liquid Solutions, Chemical Kinetics, All of Inorganic is equally important, Benzene, Aldehydes and Ketones, Amino Acids, *Perkin’s Reaction*


This section would require a lot of time to master which you don’t have. I would advise you to go through Electricity and Magnetism, Modern Physics and Thermal Physics first. These are the most scoring and the least time-consuming parts of Physics. If given a good amount of time and understood well, it could give you a good score. These 3 constitute of about 60+% of Physics syllabus.

Modern Physics should be given a greater emphasis as it is mostly a formula and calculation based section and usually, quite a good number of questions are asked from this section.

Thermal Physics is also a calculation and formula based section and require a lot of memorization of formulas.

Move on to Optics after finishing this section. This is a very broad section and requires a lot of practice and a food hold on the concepts.

At last, if left with some time, start with Mechanics. Mechanics is the most important part of Physics but still I asked you guys to leave it for the end as it a vast and a difficult part. It requires a great amount of time and strong concepts. However, if you already have gone through Mechanics before and have quite a good hold over it, I would recommend you to revise and go through this section first especially Work Power Energy and Rotational Mechanics.

Important Chapters: Thermodynamics, Current and Electricity, Wave Optics, Atomic Structure, Rotational Mechanics


Maths is the broadest and the most difficult section of all 3. It consists of Algebra, Trigonometry, Calculus, Geometry, and Vectors. You don’t have enough time to cover all these sections.

I would suggest you, to go through the Calculus part first as it is a very easy to learn, scoring and a substantial weightage part. Then go for Geometry and Vectors. These 2 again consume a lot of time but are more of calculation based sections and require a lot of practice. These 3 alone comprise about 70% of the JEE Maths syllabus.

Also go through certain parts of Algebra like Complex Numbers, Probability and Quadratic Equations. Don’t try to cover all of it. Focus on quality rather than quantity.

The most important thing in Mathematics is practice. The more you practice the better you learn, and higher the chances of solving the question on JEE Day.

Important ChaptersLimits and Continuity, Maxima-Minima, Definite Integrals, Parabola, Circles, 3D Geometry, Complex Numbers, Probability

Now summing up, you need to prepare Chemistry very well and try to complete most of the part of it. Physics and Maths on the other hand should be done with patience and more emphasis should be made on quality rather than quantity. JEE is definitely going to put up a difficult question and a light read of these chapters are not going to help you. Try to go through the chapters that I have asked you to before. However, if there are certain topics on which you have a quite a good hold and but I haven’t mentioned in the TO DO FIRST list, do those topics first and then follow mine.

Please attempt the previous year questions after completion of each topic. This is one of the most important part of JEE Preparation. Please do not forget to do this and attempt as many previous year questions as possible. Also try to attempt the previous year papers during the last few weeks.

If you are preparing for Boards too, prepare simultaneously for JEE also. Attempts around 20 questions each day from various topics during Boards. Don’t go for anything new during the last week of JEE Mains, revise key concepts like Inorganic Chemistry and all other formulas and don’t go for anything new.

If you are preparing for JEE Advanced, after JEE Mains, you still have about 1.5 months more to prepare. Continue the same strategy. Try to cover the above mentioned part first and then move on to other topics.

All the best!
