Physics is a major subject in the JEE Main exam, and it tends to define the final ranking of most of the candidates. In spite of the fact that the syllabus is very extensive, not all the chapters are weighted equally. There exist some areas in which the weightage is always high. In JEE Main, Session 1, the number of topics with high weightage and many questions is significant, and this should help the students in efficient preparation. This article describes the high-weightage physics topics to focus on for JEE Main session 1, the number of questions that students should expect, and the tips to follow in the preparation of the exam, to ensure that the aspirants can earn as many marks as possible in the exam.
Overview of Physics in JEE Main Session 1
JEE Main Session 1 for Physics is the most important in deciding the total mark because, in most cases, it is regarded as the most scoring section. The syllabus is further broken down into Class 11 and Class 12 questions. The questions primarily test the clarity of concepts, formula and inherent numeric problem-solving abilities. Physics is simplified to accommodate most of the questions, being direct and formulaic, unlike the other type of questions, which can be lengthy. The table below shows an overview physics section in JEE Main Session 1.

Most Scoring Topics in Physics for JEE Main Session 1
Physics is not a uniform subject where the same amount of work needs to be done in order to pass well. There are chapters which are slightly easier in terms of concept and formula-driven, and which are repeatedly asked in the test. These should be the most scoring topics to be focused on because even with minimal time planning to prepare, students can easily gain quick and accurate marks in the first session. The table below shows the most scoring topics in physics for JEE Main.

Common Mistakes to Avoid While Preparing for Physics
Students who lose marks in JEE Main Physics due to mistakes that can be easily avoided during the preparation phase and exam time. Knowing these can make one be more accurate and confident.
- Disregard of NCERT concepts- There are more questions in the examination directly related to concepts and theories in the NCERT books. The possible issue is the lack of conceptual gaps, due to the failure to study the NCERT books thoroughly and having to read only coaching notes.
- Learning without knowing formulas- Physics does not involve learning formulae. Students are supposed to know how and when to apply formulas and understand them in a clear manner to answer numerical questions.
- Failure to practice numerical problems- Physics requires practising problem solving to design speed, precision and being accustomed to different patterns of problems.
- Concentration on challenging chapters- The rationale of the students is to dedicate excessive time to hard chapters and topics, and to ignore easy and high-weighted courses of study like Modern Physics, Units and Dimensions or Semiconductors, which tend to offer direct questions.
- Failure to analyse mock tests- It is futile to take mock tests and not check the errors. This is because failure to analyse the incorrect answers leads to repeating such errors in the actual examination.
- Less knowledge of fundamental concepts- Mismanagement of vectors, trigonometry, graphs, and basic calculus affects grades in Physics, even though the concept was clearly understood.
- Failure to practice questions of the past year- Questions of the previous years in JEE Main contain repetitive concepts and important areas. Failing to cover them would mean that one is missing out on guaranteed-score areas.
- Studying from too many study resources- Students get confused by using various books and study sources. It is preferable to work with a few trusted content and revise it well.
- Lack of revision- Concepts and formulas used in physics become forgotten easily without revision. Failure to revise causes errors in examinations.
- Inadequate time management at practice- Taking too much time in answering a question during the exam can lead to lower scores. Balanced speed and accuracy are required in physics in JEE Main.
Last-Minute Physics Preparation Tips for JEE Main Session 1
During the remaining few days to the JEE Main session 1, revision is the subject of emphasis and attention as well as accuracy and confidence. A well strategized last minute plan can be used towards maximising scores in the exam. Use the given last-minute preparation tips for physics.
- Revise important formulas, laws, and definitions of Mechanics, Electrodynamics, Modern Physics, and Thermodynamics.
- Understand the NCERT theory and examples first, in particular, of Modern Physics, Semiconductor Devices, and Experimental Physics.
- Tackle some of the previous assessments of the past years in high-weightage chapters rather than undertaking the new questions.
- Reexamine the typical errors that occur during the mock tests in order to prevent them in the real exam.
- Time the numerical problems, while solving to enhance the speed of calculation and minimize the number of errors.
- Do not begin a new chapter or anything unknown to you at the very last minute.
- Do at least 1 full-length mock test or practice test and aim to increase accuracy instead of attempting to do it more often.
- Keep formula sheets and short notes ready for revision a day before the test.
Conclusion
Knowing the areas of high weightage in physics will be very helpful in improving the overall performance. The Physics section can be highly scoring if the aspirants will learn the questions mainly asked in each of the chapters, and will avoid making common errors or will apply a definite strategy to practice during revision. Consistent practice, conceptualization and knowledge of subjects are the key success factors in achieving good results in Physics in JEE Main session 1.
