Hi.

It is advised that you mention your rank as well, which is a deciding factor at the time of counselling. However for 97 percentile your rank should range around 26321 - 21321 and for this rank, the chances are very low for getting into IIIT-D because of very low rank closing ranks in 2020.
You can use our College Predictor tool for JEE Mains to help you in finding college and branch of your choice based on your merits in the exam.

I hope this helps
Good Luck
