For admissions in top IITs like IIT Bombay, IIT Delhi, IIT Madras, etc. for the ECE (Electronics and Communication Engineering) branch, the cutoff ranks vary every year depending upon several factors like the number of applicants, their performance in JEE Advanced, and category-wise reservations.

For general category, typically a rank within the top 500-1000 might be required for ECE branch.

The cutoff ranks for SC candidates are comparatively lower. For ECE in top IITs, SC candidates might need a rank within the top 2000-3000 (based on previous years cutoffs).

Some IITs can have specific quotas for candidates with outstanding achievements in field of sports, cultural activities, candidates from specific states and NRI's can get direct admission in them.
