I am get iiit Vadodara at SC rank 6783 with CS branch so what i can do freeze or float and i am able to get better college from this or not
Based on your jee mains category rank, your chances are high of getting admission in top colleges(private) but if you have got IIIT VADODARA then i will recommend you to float it and participate in further round and may be in the last round you can get some top colleges.
Good luck.
