NIT

Hello Suraj Sutradhar, you need to appear for JEE Advanced before admission process starts for even NIT's. JoSAA is the agency that processes the whole process of admissions into IIT's, NIT's, GFTI's & IIIT's. You need not appear for JEE Advanced if you do not intend to bid for admission in any of the IIT, but definitely need to appear for it if you intend to do so. Best wishes to you.

Hello Srishti Garg, these days raw marks do not count. What matters is the percentile. Only national testing agency will be able to tell you the percentile since they only have the data that enables calculation of the percentile. Since almost every student gives computer Science as the first choice, cutoffs in this branch are really stiff. You need to be in top bracket of percentile to get the branch of your dreams. If you get less percentile in this session, I would strongly advise you to go in for next two sessions of JEE Mains to improve on your performance. Best wishes to you.
