Hello Aspirant,

Since you have not mentioned your class so it is quite difficult to guide you with accurate source of information but yes the syllabus for class 10th has been further reduced by CISCE for 2021 Board examinations in the wake of global pandemic named COVID-19.

I am mentioning a link to the official website from where you can download the updated syllabus of any subject :-

I hope this information helps you.

Good Luck!!
