Dear aspirant ,

The top 5 NITs of India can be named as NIT Trichy, NIT Rourkela, NIT Surathkal, NIT Warangal and NIT Jaipur. You will need to score a minimum of 98 percentile in JEE mains paper to get admitted in CS branch in one of the top 5 NITs of India. Considering them through other state quota this is the minimum percentile you must get. Though the cutoff for CS in NIT Trichy might also get closer to 99 percentile as it's considered the primary NIT of India and everyone considers studying there first.

Hope this helps!
