All the best.

A minimum of 75% or 20 percentile in your state board (for General and OBC) and a minimum of 65% or 20 percentile in your state board (for SC/ST) is required for the B.Tech programme at BIT.

You have to appear in B.Ed first because B.Ed is the minimum qualification for M.Ed.

First of all you need to pass 12th with minimum 45% for admission in any college. You need not to be above 24 years. JEE is a must nowadays except for some private colleges. If you want a seat in NIT or IIT you need to crack JEE Mains and Advance. For admissions, you need to get atleast 70% in 12th. Relaxation is there for SC/ST candidates.

The syllabus for UG programme is based on class 11th and 12th. So, I would suggest you cover all the mathematics topics of class 11th and 12th.
