IIT Mandi - Indian Institute of Technology

For taking admission in IIT BHU, you need to clear your JEE exam.

No, it has no benefit but you have to pass mpc and a language and any other subject to get an admission in IITs. 12th marks are for our performance check only.

Hello Vaishnavi Singh, oh don't worry. Losing confidence while preparing for major events is a pretty common occurrence in humans. But our inner resilience invariably takes us out. Of course, if you continue to have it for longer periods then only it becomes a cause of concern. You must think, what is going to happen if you don't make it to IIT? In any case, 95% of students appearing for JEE Mains examination can not make it to IITs. It's not the end of the world. As matter of fact with the same preparation and almost at the same cost, you can go to it, the USA for undergraduate studies!
Best wishes to you.

No In IIST there is no seperate JEE exam. For admission IIT JEE entrance examination marks would be considered.
