Hello sir,

Hope you are doing great.

So according to your question, first of all, Amritha University will only accept AEEE, and the cutoff for the CSE course is 96 to 99 percentile. As he got 87.4 percentile, he might not get the seat in CSE.

However, he also secured 90.4 percentile in JEE Mains, which is a very good score, and he can secure more in the second phase, there are very high probabilities for that. So, if he manage to score between 97 to 99 in JEE Phase 2, then he will definitely get IIT or NIT.

So, don't loose hope and don't let him loose the hope.

Thank you!
