JEE Mains 2020: Important topics & Their Marking Weightages

JEE Main is a national level engineering entrance exam. As per an outstanding opportunity to join the engineering courses like B.Tech, B.Arch & B.Planning, the competition remains tougher every year.

One requires a positive attitude, a pinch of passion and smart work with intense dedication and properly channelized guidance to qualify this examination.

But let’s face the truth that the syllabus of Mains exam is huge. It includes two papers i.e. Paper 1 & Paper 2. Paper 1 is compulsory for all but paper 2 is only for those who want to join B.Arch/B.Planning courses. Paper 1 includes three subjects i.e. Physics, Chemistry & Mathematics. Whereas Paper 2 includes three sections i.e. Mathematics, Aptitude & Drawing.

To make preparation easy for Joint Entrance Examination Mains for you, here we have come up with the list of important topics from JEE Main Syllabus and their marking weightages.
