Hello aspirant,

Congratulations for your results. Hope you are doing well. IIT are the topmost technical institutes of India and every student wants to go there and CSE branch is the most preferred branch among all the other branches so the cutoff for the CSE branch is very high. Admission also depends on various factors such as category, home state quota, branch selection, number of students applied, number of seats, difficulty level of examination, etc. 

Now 985 is your which category rank either general, obc or sc/St. Well with this rank you are having chances of getting CSE in new IITs such as IIT Ropar, Tirupati,etc. It majorly depends on your category rank and home state quota also. For a better understanding you can go through the previous years category wise cutoff for CSE branch
