Hi aspirant,

At first I would like to wish best of health to you and may you recover soon. Coming to your question you can surely take a a drop this year and appear for the examination next year if you are not comfortable in appearing for the same. The registration in CBSE for classes 10&12 are valid for next 2 years from the day of registration and you would just need to contact your school to put your name in the list of candidates.

Also you must note that it would be a completely new start and no previous records of your term 1 examination would be taken into consideration for next year.

Hope it helps!!
