How to Prepare Most Important Chapter for JEE Main 2023?

Physics:

  • The Oscillations and Waves chapter contributes to around 10% of the exam questions. In addition to these subjects, questions from Electrodynamics, Modern Physics, Optics, etc. have appeared in prior examinations.

  • A student should therefore begin by studying these subjects since they were commonly included in the papers from the previous year.

  • You can choose the simplest topics, such as Unit and Dimensions, Measurement of Errors, and Vectors.

  • Your preparation for Physics will be on point if you understand the concepts of each topic, earning decent scores in it.


Chemistry:

  • The chapter on Organic Compounds Containing Oxygen has the most questions on the JEE Main exam. The above chapters mentioned in the table are always the most crucial for JEE Main 2023 and will surely be tested.

  • The next crucial ones are Organic Compounds Containing Nitrogen, Redox Reactions, Biomolecules, Electrochemistry, Atomic Structure, Polymers, Solid State, Some Basic Concepts in Chemistry and Classification of Elements, and Periodicity in Properties.

  • The simpler chapters are Hydrogen, States of Matter, Hydrocarbons, Surface Chemistry, and so forth.


Mathematics:

  • Limits and Continuity, Quadratic Equations, Permutation and Combination, Complex Numbers, Circles, Binomial Theorem, Sequences and Series and Differential Equations are the most crucial chapters.

  • The simpler and less important chapter for JEE are Inverse Trigonometry, Heights and Distances, Application of Derivatives and Statistics.

  • Foundation based on Sets, Relations and Functions everything needs to be learned from scratch.

You will boost your chances of getting a higher math score if you practise and answer 4 to 6 questions from each section each day.


Tips for JEE Main Important Concept

Speed:

  • Students will become faster at basic topics with more practise.

  • During the test as well, this speed must be maintained.

  • There is no sectional timer, so make sure you finish answering enough of the questions in each part in the allotted one and a half hours (90 minutes) so that your score passes the desired cutoff.


Mock Tests:

  • Practice papers and mock exams actually show how much preparation is required.

  • Mock test enables the applicants to guess the difficulty of the exam and the effectiveness of their own preparation so they can focus on their weak topics.

  • In order to evaluate accuracy, effectiveness, chapter knowledge, and exam completion time, mock exams can now be completely checked online.


Accurate Answers:

  • Try to answer as many questions as you can, but with accurate answer, rather than focusing on answering maximum questions.

  • This will increase your score and probably add to the overall rank considered for IITs.


Revision:

  • Plan out when you will study and revise.

  • Take periodic breaks and review JEE Main exam papers from prior years.

  • Study important topics and chapters every other day, or at least twice a week.
