Three month is a very long time for people who have the right attitude to make it possible. It’s not the task which is unachievable, it’s what you think that it is unachievable. So, challenge yourself, and start preparing right now to make it happen. Divide each chapter as per its importance and start revision followed by rigorous practice. Firstly, memorize the easiest topics to score good marks in direct questions. All you need is smart study in these three months. Read more to know how to crack JEE in 3 months!
You must study for about 10 to 12 hours daily and increase the number of hours by one hour every upcoming week. In fact, you will also be studying for your CBSE/ICSE/State boards as they are going to take place during the same year. Divide your time between JEE and boards judiciously. No need to give extra attention for the boards preparation, as 80% is more than enough.
How to crack JEE in 3 months: PHYSICS
The most important thing in learning physics for JEE Mains as well as JEE Advanced is understanding the concepts very well. If you don’t understand the concept behind a given problem, you will never be able to solve a JEE Physics question regarding that topic.
It’s important to study from good books of JEE Main and JEE Advanced. Some of them are listed below:
- NCERT Physics Textbook (class 11th and 12th): NCERT textbooks contain some of the basic concepts explained very well, such as Semiconductors & Electronic devices and Communication System (important topics from JEE Mains prospective).
- HC Verma- Concepts of Physics (Part I & Part II): The only thing you can do in these three months is to attempt solved examples followed by few unsolved questions of that chapter.
- Understanding Physics Series (Set of 5 Books) by D. C. Pandey (Arihant Publications): These books contain a large number of solved and unsolved examples on particular chapters. No need to solve the entire chapter. Solve only from the subjective section.
Important Chapters/Topics which carry maximum weightage
- Kinematics: Very simple questions are asked from this in JEE Mains (NCERT Based). For JEE Advanced important topics are Projectile motion and Relative motion. Problems on Relative Motion given in H. C. Verma would be more than sufficient.
- Newton’s laws of motion and Work, Power & Energy: Key to solving problems on these chapters is knowing how to draw a free body diagram (FBD). There is 90% chance that if a question from this chapter arises in JEE Advanced, then it will be definitely related to the drawing of Free Body Diagram.
- Simple Harmonic Motion (SHM) & Oscillations: Most important type of questions that are asked in JEE from SHM is finding time period. The only way to tackle these problems is by using energy conservation method.
- Heat & Thermodynamics: Calorimetry, Heat conduction in one dimension, Isothermal and adiabatic processes only, First law of Thermodynamics and its applications (only for ideal gases) are the major topics.
- Electrostatics & Current Electricity: Coulomb’s law and Gauss’s law govern the entire electrostatics. A good practice of the application of Kirchhoff’s law will enable you to solve many problems on current and electricity easily.
- Modern Physics & Radioactive Decay: Read this topic thoroughly from H. C. Verma and NCERT. Mostly data based questions are asked from this chapter. Nuclei and atoms are very important from JEE Mains perspective.
How to crack JEE in 3 months: Some Basic Tips
- Numerical problems in JEE Mains may involve some very lengthy calculations, so be prepared for it and develop your speed accordingly.
- Mug up the Frequency range for each kind of Electromagnetic Wave. Theoretical chapters such as Communication System and Semiconductors are of utmost importance for JEE Mains. There will be at least one question from each of these chapters in JEE Mains which if studied properly is scoring.
- Having a good command on Electricity & Magnetism will definitely give you an ‘edge over others’ because it has a huge weightage in the JEE Advanced paper.
- Electromagnetic induction and Alternating Current are one of the easiest chapters and simultaneously important too, it is a bad decision to leave the questions from this section which many students do.
How to crack JEE in 3 months: CHEMISTRY
You should consider Chemistry as seriously as Physics and Mathematics. You must understand that it is very important to mug up as much as possible properly in order to learn Chemistry. Also, there is also a possibility of forgetting things so revision is very essential. With an appropriate planning and schedule in these three months, you can make Chemistry your most scoring subject out of three.
For JEE Mains, NCERT would be more than enough. But for JEE Advanced, go through reference books like:
- NCERT: This is to be for sure the most important book for Chemistry as far as JEE is concerned. You should be comfortable with each and every line of NCERT in each of the Inorganic, Physical and Organic part. Most of the Inorganic questions are asked directly without any twist.
- Organic chemistry (O. P. Tandon): No need to read the theory part from this book, rather practice some advanced level problems.
- Inorganic Chemistry (J. D. Lee): Read only those topics which are there in JEE Syllabus, but not given in NCERT. This book is easily available online in pdf version so you don’t need to buy it.
- Physical Chemistry (P. Bahadur): It has a variety of numericals to make your concepts strong.
Most Important Chapters/Topics carrying maximum weightage
- Chemical Bonding: A basic chapter whose concepts are used in entire organic chemistry. Direct questions are always asked from Dipole moment and VSEPR theory.
- Chemical kinetics & Equilibrium: Special attention must be given to 1st order reactions, Le Chatelier’s principle (effect of concentration, temperature, and pressure).
- Named Reactions in Organic Chemistry: A large portion of organic chemistry consists of named reactions and you are expected to know these reactions along with the complete mechanisms stepwise.
- Electrophilic aromatic substitution reaction of Benzene and its derivatives: Utmost important topic, questions from these are definitely asked.
- Coordination compounds: Stereoisomerism, Geometry and shapes of Tetrahedral and Octahedral complexes, Crystal field theory.
- Metallurgy: Mainly standard questions are asked from NCERT. Carbon reduction method, Self-reduction method, Cyanide process are important topics. Direct questions are asked and so you need to be thorough with the metals.
How to crack JEE in 3 months: Some Basic Tips
- Don’t try to simply mug up the reactions of organic chemistry, this is not a decent practice. Try to understand the complete mechanism behind it and once you know it, learning comes naturally.
- You need to note down important formulae & reactions separately. Revising these on a daily basis will enable you to review everything from memory.
- Questions of organic chemistry should be attempted at the end after completing the questions of Physical and Inorganic part, as they are less time consuming.
- For numerical questions, you must revise shortcut formulas which would enable you to arrive at the answer quickly and hence, save time.
How to crack JEE in 3 months: MATHEMATICS
With only 3 months in hand, you must develop a strong conceptual base along with the skill to solve problems that involve aptitude and lengthy calculations. Mathematics paper of JEE is highly unpredictable. A general trend noticed states that a question involving multiple concepts is asked. For instance, many questions involving concepts from both permutations & combinations and probability are asked in the paper. So, you must be prepared for everything that comes in the paper with a confident approach.
- NCERT mathematics or R.D. Sharma: You must have solved all the problems from each chapter properly for boards. Now figure out problems which you were not able to solve at one go, and attempt these problems.
- IIT Mathematics by ML Khanna: I will advise you to solve only objective section of this book before JEE Mains and the Subjective part after JEE Mains for JEE Advanced.
- Conic sections: Key to solving a problem from this chapter is knowing the formulas very well. Most of the problems of conics can be solved easily by applying the parametric form.
- Calculus: At least 8 questions in JEE Mains (4 from each Differential and Integral Calculus) is asked and this topic has 30 to 35% weightage in JEE Advanced.
- Vectors & 3D: Constitutes 20 to 25% weightage in JEE Advanced, knowing how to visualize the situation would be helpful in solving the questions.
- Permutations & Combinations and Probability: These are those chapters in which you have to use your ‘brain firstly’ and then ‘apply mathematics’. Most of the times Paragraph type question is asked from probability.
- In case of single choice questions, you can easily go with an objective approach, i.e. you can either substitute those values given in four options or eliminate the options.
- In case of Coordinate Geometry, you can make a rough graph and plot the points or try to plot the points given in the options so as to satisfy the equation.
- Generally many multiple correct options are linked to each other, hence if you somehow find the correct answer of any one option, the others can be quickly solved.
- In case of Indefinite Integration, you can easily differentiate the given four functions, in order to find the correct answer. This will help to save time.
