Hi Muvvalaakhil,

According to your marks and rank there might be a possibility to get the iiit or nit but according to me CSE is difficult so you have to go for the counselling till the last round to get better college with better branch. College is also based on your state because state quota is available in every college. But rather then CSE their are more options of branches are open for you and for CSE you have to go for iiit's their might be a chance to get cse branch.

Before that you can go through the below link to predict your college:- https://engineering.careers360.com/jee-main-college-predictor?icn=QnA&ici=qna_answer

I hope this information is helpful for you.

Good Luck!!!
