JEE Main 2025: Rank Predictor | College Predictor | Marks vs Rank vs Percentile
JEE Main 2025: Sample Papers | Syllabus | Mock Tests | PYQs | High Scoring Topics
Apply to TOP B.Tech/BE Entrance exams: VITEEE | MET | AEEE | BITSAT
With this rank, chances of getting lower NITs are decent as this is quite difficult to get into top NITs so it would be good if your son works little more hard work and get score 230-270 so that he can easily get seat in top NITs in top branches like CS, ECE, EE etc.
