Mathematics, being calculative in nature, requires a special analytical approach towards problem-solving. The Mathematics section in JEE Main 2021 exam will carry 30 questions. There will be two sections i.e., Section A and Section B. Section A will be comprised of Multiple-Choice Questions (MCQs) and Section B will consist of questions whose answers are to be filled in as a numerical value. In Section B, candidates will be required to attempt any five questions out of 10. There will be no negative marking for Section B. However, in Section A, any question answered incorrectly, one mark will be deducted.

In JEE Mains 2020, the highest weightage in Mathematics was given to chapters like sequence and series, straight lines, 3D, Determinant, etc.
