Central Board Of Secondary Education [CBSE] — Regarding the schedule

Soo basically, I study in class 10 and I have opted for sanskrit
The problem here is that we dont have a single day leave for sanskrit exam and due to online classes we didnt understood much and for science we have extra days for study you can change the time table
Or else Cancel the boards exam due to the rise in covid 19 cases
You can also conduct exams online as it will be safe for students and everyone can get good percentage
Thank you
