# IIT JEE Examination 2021 Syllabus

Getting into India's most celebrated institutes need preparation that is above par. To achieve that level, the first thing that needs to be done is to cover maximum topics and concepts as possible.

## JEE Main and Advanced 2021 Syllabus

JEE Main Paper 1 and JEE Advanced Paper 1 and Paper 2 consist of three sections in each paper, namely: Physics, Chemistry, and Mathematics.

### Physics:

The Physics portion of the test will have 30 questions. The complete physics syllabus can be broadly segregated into the following 5 sections i.e.

- Mechanics
- Heat and Thermodynamics
- Electrostatics and Magnetism
- Current Electricity and Electromagnetism
- Optics and Modern Physics

### JEE Main Paper 1 Weightage:

Out of the above mentioned sections, there are some topics which carry more weightage as compared to the others, in JEE Main Paper 1, they are as follows:
