JEE Main Physics section syllabus consists of topics from Class XI and XII, in the ratio as specified by NTA. Physics contributes a total of 100 marks to the paper, the complexity of the section increases further when two topics are intertwined to form a single question, a very common practice observed in JEE Main physics questions.

Tips by IITians and Experts

## Maximising Your Score in JEE Main Physics Section - Tips by IITians and Experts

It’s very essential to not just understand the topics but also have a plan in terms of handling various topics. Candidates should have a clear understanding of their grasp on various chapters, they should work on the ones they find difficult and make sure that they score when they find a question from the topic they find easy.

For the assistance of candidates, we have some specific tips on how to handle various topics by IITians and subject experts, candidates can take them into consideration while devising their own plan:

### Mechanics: Weightage and Tips

Mechanics is one of the fundamental units in JEE Main Exam comprising nearly 35% of JEE Main Physics Syllabus. Mechanics thus becomes a quintessential part of your preparation.

•  Following the past trends, questions correspond to the following chapters in their descending order of weightage: Rotational Motion, Waves, Units & Dimensions, Oscillations, Work, Energy & Power, Gravity, Mechanics of Solids & Fluids, Laws of Motion followed Kinematics. Some Important topics for your preparation having a higher probability of them being asked in the exam are Dimensional & Error analysis, Equations of Motion, Relative Motion, Simple Harmonic Motion, Kepler’s laws, Projectile & Circular Motion, Satellites, Mechanics of Common Forces, Potential Energy of a spring, Acceleration due to gravity, Transverse & Longitudinal waves-superposition and reflection, Moment of inertia and dynamics of Rotational Motion. The list, however, is not exhaustive.

• HC Verma Physics is considered to have your basics in place, followed by practicing examples from DC Pandey. IE Irodov Book could be used to practice more complex questions. Solving Previous Year Question Papers is a must to know if your strategy and resources are accurate.

• For Preparation, ensuring conceptual clarity and logical consistency is of absolute necessity.

•  Questions need to be solved in a stepwise manner. Ensure you don’t follow short cuts even in your practice registers. The contextual method in your practice helps you improve pace & precision.

• If with your planning, you feel marginally comfortable, you can continue by considering answers to challenging problems and then seek to attempt certain problems without answers.

• More so, the logical thinking methodology, the analytical reasoning and decision making would ensure that you create a niche for yourself. This resonates with you by associating your theoretical learnings with real-life examples. Even if you are able to begin this process, this will stimulate your thinking and would develop further. Mastering it should not be your concern. Furthermore, time & stress management is of utmost importance.

• Self-Analysis and self-designed strategy by way of taking numerous Mock Test Papers & consistency in your study routine is key to ace an exam.

### Optics and Modern Physics: Weightage and Tips

JEE Main Physics questions range from thermodynamics to electromagnetism and as important as these topics are, optics and modern physics are certainly a major part of the exam. Considering optics alone, you can expect 5-6 questions in the examination, and 8-9 questions for both topics. That means that these topics are around 30-33% of JEE Main Physics Syllabus.

• NCERT questions at the end of each chapter can help you to get started with the preparation.

• If we go by the historical pattern, just studying these topics won’t be enough to get a good rank in JEE Main. Please keep that in mind, you need to score at least 50% marks to have a good rank.

• Some reference books that are good for these topics are:

 Arihant’s Understanding Physics for JEE Main and Advanced Optics and Modern Physics Understanding Physics: OPTICS & MODERN PHYSICS by DC Pandey Cengage Physics for JEE (Advanced): Optics & Modern Physics by BM Sharma
• A former IITian comments, “I found Understanding Physics by DC Pandey to be most helpful in my case as the solutions were easier to understand. Of course, one of the best books to cover optics and all other topics as well, is HC Verma. Don’t just rely on these reference books. Some solutions may be difficult to understand at first, but according to JEE Advanced, this level might not be too high.”

• One of the keys to crack JEE is to write mock tests as much as possible. It gives you the idea of the examination as well as how much time you need to divide for each topic. The more mocks you write the better are your chances of making it to an IIT or any institute that you have in mind. Don’t skip any fundamentals, clarity boosts up confidance.

Difficulty Level Analysis

## Difficulty Level Analysis for JEE Main Physics 2022

The level of difficulty of JEE Main Physics section varies in different sessions. For the understanding of candidates, a basic distribution of number of questions in terms of difficulty level of B.E/ B. Tech paper of JEE Main previous session is tabulated below:

Sections

Tough

Medium

Easy

Chemistry

4

11

10

Mathematics

2

10

13

Physics

16

Although as per the above analysis, physics seems to be the easiest section in the January B.E/ B.Tech paper but candidates must keep in mind that level of difficulty is a subjective concern and different candidates can have a different perspective on the question paper.

Preparation & Attempting Tips

## JEE Main Physics - Preparation and Question Attempting Tips

Physics section plays an important role in both JEE Main and JEE Advanced, it can be a rank uplifting section for some. Candidates operate on different levels of caliber, we have devices some tips that can be helpful to all the candidates:

• Make topic-wise short notes of formulas and facts: This is something you can do while your preparation and also when you solve problems. It may seem like a basic strategy but it proves highly essential for memorizing and retaining information.

• 3 hours of Physics per day: Make sure that you balance your preparation among the three subjects i.e. Chemistry, Physics and Maths. Giving 3 hours to physics on an average should be more than enough. Candidates must keep in mind their strong and weak zones before making their time table.

• Don’t jump on conclusions: Candidates often jump on conclusions intuitively while solving the questions. If you find yourself doing this mistake then try to write the information given in the question separately to make sure that you rely on facts while problem solving.

• Read the Question at least twice: Don’t panic if you can’t seem to get the question. Read the question carefully again, generally the information that can lead you to the answer of the question is hidden in the statement.

• Accurate Problem solving approach: During your mock tests and practice papers, keep in mind that solving every question requires the right approach. This approach must include first understanding the question followed by application of concepts and ultimately calculation.

• Practice with Previous Year Papers and Mock Tests: Practicing is the most essential component of your preparation as per all the experts. Practice and analyze your performance constantly to know the productivity of your current plan.

• Revise at Regular Intervals: Most often than not candidates wait to cover the entire syllabus and then start revising. However, to keep your hold on concepts fresh, you must revise at regular intervals. This will also save your time when you sit for complete rounds of revision.
