Hello aspirant. Congratulations on your score. according to your percentile and the category you specified, your rank would be around 67,700. Which is comparatively really higher rank. So the chances for you to get Computer science branch in NIT's or IIIT's is really less in first counselling. I would suggest you to go for some other branch. If not Computer science, ECE,EEE are also the better branches provided you have interest in physics. Here i provide the link below so that you can have an idea of what colleges you would be getting

All the best

Regards
