Hey Harshit,

You can get admission in IIt Roorkee by passing jee advanced with good rank.

IIT Roorkee is one of the most renowned colleges of India in which admissions are not easy you need to work hard and learn the fundamentals of all 3 subjects physics, chemistry and maths thoroughly.

For admission into IIT you need to crack jee advanced but before advanced you need to pass jee mains with 75% 12th board marks(Gen category).

Jee advanced is conducted by an IIT which is conducted in two papers (now both online) both of 3-3 hours each.

All the best
