Hello aspirant,

Well done for your score, but still you need to improve it. So prepare well for second attempt of April. I'm saying like this because with 77 percentile getting a seat in IITs or NITs is very much difficult, and your category also will play a major role. So study hard for next attempt. But I'm not saying you won't get a seat, I'm just wanna say that probability is less, you can use College predictor for your reference. Here is the link:

Hope this data helped you, Thank you.

All the best!!
