Hi sneha,

Hope you're doing good.

I'd suggest you to PLEASE do whatever you like. You don't wanna become a doctor who doesn't like community service and her job. Rather, be an engineer who likes what she does for a living.

As most of the colleges have closed their admissions,  there are still some colleges left. And regular courses always have more value than open schooling. So you should apply for regular course and side by side prepare for JEE. Else, you can still pursue open schooling in maths and prepare For JEE, it'll help you a lot. You'll have plenty of time.

All the best.
