Dear Student,

Yes you can get PSIT Kanpur but it will be more better if you go with the direct admission as if you try through counselling there is a chance that you can end up by getting some other branch besides CSE because your rank is too much.

And you don't need to register in the UPCET because this is for the lateral entry and other courses students. To take admission in 1st year of B.tech you need to register yourself in the UPSEE counselling then you can select your college through JEE mains score.

Good Luck :)
