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.

  1. Mechanics
  2. Heat and Thermodynamics
  3. Electrostatics and Magnetism
  4. Current Electricity and Electromagnetism
  5. Optics and Modern Physics

JEE Main Paper 1 Weightage:

The JEE Main Paper 1 will have 30 questions which would be numerical and theory-based and for the correct answer, the student needs to select one option from a choice of 4 options. The Chemistry syllabus can be segregated into broadly three sections i.e.

  1. Physical Chemistry
  2. Organic Chemistry
  3. Inorganic Chemistry

Further, based on the past JEE Main Paper 1 tests, the expected weightage of the different topics across chemistry can be bifurcated as follows:
