JEE

Based on your percentile, it is not possible to get a seat in any NIT or iiit. Even obtaining a seat in the new iiits via CSAB special round counseling seems very hard. Now coming to other government colleges, you can apply to the colleges accepting admission through JEE Mains. As I have heard, maybe UPTU is planning to take admission by JEE Mains. Look to it, this is not confirmed. Apply to other state colleges accepting Mains result. Give other exams too, I am sure you can get good rank in state exams. Or the other option left for you is to prepare again for JEE and do better this time, you will atleast need a percentile near to 97.5 percentile and above to secure a seat in central colleges considering your category. Try and choose wisely if you are going to take admission this year, do not go for Mains counseling, it would be a waste of time.

In the absence of your category-based rank, it is difficult to accurately answer if you can or cannot get NIT-Andhra Pradesh (Tadepalligudem). But based on the previous year's cutoff for B.Tech in the Computer Science and Engineering branch, it could be said that you cannot get NIT (Tadepalligudem) if your general category rank is not under 17,400 in JEE Mains. The reason is that CSE is one of the top branches, and therefore the competition is high, as evident in the 2020 and 2021 cutoffs. For example, in 2021, the general college rank for admission was 17348 while it was 14025 in 2020. Even with category-based exemption, one must have a rank of less than 20,000 to be admitted to the NIT, Andhra Pradesh.
