4. How to crack JEE Main 2022 Physics in one attempt?
The JEE Main 2022 Syllabus is the first step in beginning the preparation. Students should thoroughly comprehend the complete syllabus to understand what questions can be asked in the JEE Main 2022 examination.
Without the syllabus and exam pattern, it will be extremely difficult, if not impossible, for students to pass the JEE Main 2022 Physics examination. As a result, students must familiarise themselves with the JEE Main 2022 Physics syllabus and exam pattern.
Accordingly, students must plan their entire day. A study plan acts like a roadmap to achieve the desired results.
Practice several questions, sample papers and previous year’s questions. Students must practice the JEE Main Mock Test Online 2022 – Register Now For Free for better clarity of concepts.
5. Which chapters can I skip from the JEE Main 2022 Physics Syllabus?
NTA has scheduled the first session of JEE Main from 20 to 29 June 2022, and the second session from July 21 to July 30, 2022. Students taking JEE 2022 must prepare as JEE Main session one is around the corner.
While many students must have completed the JEE Main 2022 Physics Syllabus on time, many students are still struggling with it. Subject experts generally advise avoiding skipping any topics because each topic is important in the examination. However, if students are short on time, they can skip the following chapters:
- Laws of motion
- Principles of Communication
- Centre of mass and collisions
- Circular motion
- Heating and Chemical Effects of Current
