With a OBC Rank of 8.6k in JEE Main, you have fair chances of securing CSE at many good IIITs like Vadodara, Pune, Bhubaneshwar and many others.  Incase youre from North India and have craze for studying in vicinity of Delhi NCR, you may perhaps choose CSE Dual Degree at JNU Delhi. Youll even get CSE at some of the North East NITs like Mizoram, however I would advise you against going to these Institutes, cause lower Placements.
