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.
