JEE Main 2020 is around the corner, and with month-long national lockdown, some students are now thinking about JEE main 2021 syllabus. Many experts and students are currently discussing the JEE Main 2021 syllabus, whether the syllabus should be reduced or not as the lockdown has reduced the number of days for preparing for next year JEE main exam.
The official notification of jee man is generally released in September-October after that students start preparing for jee main exam. The aspirant now can focus on all the engineering entrance exams. However, the situation is little different as the board exam are postponed, and students don’t have enough time for preparing for the exam
COVID -19 has created a more significant impact on the education industry, as of April is always the critical month of any engineering aspirant. Although CBSE has decided to reduce the syllabus, NTA is yet to decide on reducing the syllabus of JEE main.
Will NTA reduce the JEE Main 2021 Syllabus?
JEE Main 2021 aspirants are demanding jee main syllabus to be reduced because of the less time this year for preparation. All these situations will be evident by NTA only; however, the reduction in the syllabus is speculated.
According to the experts, NTA may deduce in reducing the syllabus because of less number of days for jee main preparation because of COVID-19. However, jee main aspirants are advised to prepare as they use to do it earlier.
