Hi Sagar,
I hope you are aware that you must complete your Bachelor's degree to pursue MBA. Good academic grades, throughout from (class 10th, 12th and Bachelors) is preferable. I also hope you know where Harvard stands. It is one of the top most universities in the world. You must not only have good academic grades but also be an all-rounder. Visit their websites and check the admission requirements. You can prepare accordingly.

No, just maths/computer science in class 12th with 60% aggregate.

Dear,
The eligibility criteria:
Completed class 12th from CBSE or equivalent board with a minimum of 50% aggregate and must have passed English (core or elective or functional) as a subject.
As per this, you are not eligible.
Even you can complete your graduation in any stream and then go for LLB programme but in that case, you should have 50% in graduation.
You need to consider other options.
All the best.
