Hello,

• Important chapters for JEE Mains: Physics

Physics contains a number of memory-based chapters towards the end of the course which are specific to JEE Mains only. Some of these chapters are namely, semiconductors, communication systems and modern physics. Students generally try skipping these chapters. Skipping these chapters completely isnt advisable since it fetches easy marks and they are always asked in some or the other way in JEE Mains.

In case of a lack of time preparing them from summary sheet would help a lot. Here is a list and details of chapters that you should definitely not skip while preparing physics for JEE Mains:

• Electrostatics: This chapter is a part of the syllabus of class 12th and is asked very frequently in JEE Mains. The number of questions asked from this chapter is also more in number comparatively.
• Atoms and Nuclei: This chapter is almost the last chapter of the entire JEE syllabus and is considered to be boring by a lot of students. Since it is generally a JEE Mains specific topic, students tend to skip it. However, this topic is an important one and might have more than a single question. Also, it will fetch easy marks and thus, shouldnt be skipped entirely.
• Oscillations and Waves: This chapter is full of formulas and is also asked in an easy form in the exam. A little emphasis on it would fetch you some easy marks.
• Current electricity: This chapter is pretty much analogous to electrostatics and is also taught in class 12th.

The above chapters were the most chapters of the lot. However, dont skip chapters entirely for JEE Mains. But yes, you should be thorough and perfect with the above mentioned important chapters.

• You can also consider Modern Physics and magnetism as important topics too because from last year's paper questions were asked a lot.

Good luck.
