With a 90 percentile in JEE Main, you have a good chance of securing admission in government engineering colleges, in less competitive branches or newer NITs and IIITs. For top branches like CSE, Mechanical, or Electrical in older NITs or IIITs, admission might be more competitive, especially without a very high category rank. You can check the previous year cutoff trends of the various colleges by visiting their official website and participate actively in counseling to maximize your chances based on your preferences and rank.
