JEE Main 2020 Mathematics Syllabus
The Mathematics section of JEE Main 2020 will be of 100 marks (25 questions of 4 marks each). However, for any question answered incorrectly, one mark will be deducted. In 2019, the highest weightage in Mathematics was given to chapters like sequence and series, straight lines, 3D, Determinant, etc. Check out the detailed JEE Main January 2020 Paper 1 syllabus for Mathematics.
