Hello Aspirant,

See there is no any fixed minimum marks  required to be eligible for admission in good engineering colleges such as NITs or IIITs or any government engineering colleges for any category because the seat allotment process is based on the rank of candidate but if you are a PwD candidate and wants to get into any government engineering college like good NITs then you should at least try for 40-50+ marks out of 300 in JEE-Main 2022 and for state government engineering colleges, 20+ marks will also be the decent score .

You can check out JEE-Main Learning package for solving series of mock tests :-

I hope this information helps you.

Good Luck!!
