IIIT

Dear aspirant, Glad to meet you. According to recent year rank: NIT GOA AND NIT ARUNACHAL PRADESH closing rank is near to your rank so checkout for this college. Your score is good but According to your rank, it is unlikely for you to get computer Science in any NIT or IIIT even the lower ones. Generally the closing gen category rank for CSE in all institutions is around under 20,000. Although you may get other branches such as Civil Engineering, Chemical Engineering, Metallurgy, etc. In good private universities. You can also explore private colleges accepting JEE Mains score if you wish to pursue Computer Science only. Hope it helps. If you found it useful then upvote or thumbs up my answer. Good luck.

Since there are more alternatives in civil for government jobs, I can infer that you want to study M.Tech but not PSU if you want to succeed in GATE CS. I am listing the materials a kid will require for preparation since I was a GATE aspirant:
a solid, well-organized course. Good assistance with clearing up doubts from a coaching facility. Cost-effective. Encouragement and morale to maintain discipline. I am a former made easy student who is currently enrolled in an applied course, and I can report that the majority of coaching facilities only offer the first and second points during coaching not after. But I've received all four from applied courses.
