Hello Aspirant.

You've scored 90.34 percentile in JEE mains and also belong to ST category. At this rank you might get lower NITs but getting a high branch would be a problem or even you can apply for semi government or Private universities. You can apply for IIITs , DTU but getting high branches would be a trouble in all these cases.

You can still apply for colleges such as Thapar University, Chandigarh University etc. Here you'll be able to get high branches

Best of luck !
