Getting admission to PSIT Kanpur, with a UPTU score of 208 will be difficult, especially in popular branches. You can opt for the branch you are getting admission to and apply for branch change in the second year.
The college also offers direct admission based on merit. You can apply for the direct admission option as well.
One of my relatives has completed his B.Tech CSE from PSIT. As per his insights, it is better not to opt for any private institute or PSIT with such marks.

Drawbacks of PSIT
Overall, you will get admission in PSIT either through UPTU or through Management Quota. But it is better to go ahead with any government college.
