JEE MAIN 2021 Syllabus Reduced? Check the list of Topics

This is the most trending question on internet nowadays students are worried about JEE Mains 2021 because of the current condition due to COVID-19 and schools and coaching centers are closed that’s why student will not going to have enough preparation time for JEE Main 2021.

So, Yes according to the sources and rumors on internet it is possible that NTA can reduce up to 30% syllabus of JEE Main 2021 and examination can be held on in August 2021 so that candidates can get enough preparation time. Also as latest announcement of Ministry of Human Resources and Development (MHRD) on CBSE class 10th and 12th final examination that 30% syllabus will be reduce in Examination so possibly this 30% can impact on JEE mains 2021 Syllabus.

Will JEE main 2021 Syllabus be reduced?

Yes the chances of syllabus reduction is quite high as JEE Main Syllabus is same as the syllabus of 12th class and 30% syllabus is already reduced by CBSE Board. Although there is no official announcement yet from National Testing Agency (NTA) regarding reduction of syllabus but NTA can announce reduction in syllabus in Information brochure of JEE Main 2021.
