Hello Aspirant,

Since you have not mentioned that name of board for which you want to appear so it's quite difficult to guide you with an accurate information of syllabus.

If this is for CBSE board then the board has reduced the syllabus of Class 12th for the academic year 2020-21 which you can get from the link given below :-

On December 31st 2020, at 6:00 PM Our Hon'ble Education Minister Mr. Ramesh Pokhariyal Nishank was live on his social media handles and he did announce that the CBSE board exams for class 10th and 12th for session 2020-21 will start from May 4th 2021 and will be completed by June 10th 2021 and after this the results will be declared by July 15th 2021. He also announced that the practical examinations will commence from March 1st 2021. The dates are decided in keeping the view of student's concerns so that they can get proper time for preparation.

Usually, the CBSE board exam starts in the month of February. But this year, exams have been delayed to compensate with the study loss during the closing of schools because of outbreak of Corona virus.

I hope this information helps you.

Good Luck!!
