Hi,

The closing rank for CSE in PES college was 56816 last year . So you have very high chances of getting there. Other than that , according to last year cutoods you will also get CSE at MS engineering  college, at days and Sagar university and many other colleges. These is according to 2018 cutoffs. Any further doubts , ask me in the comment section

Best of luck 

Dear computer science is the most demanding branch in the recent trends so you can go with computer science but as per your rank might be less chance you get cse branch with this rank because CSE is the most referenceable branch and mostly topper of any exam might be 1-1000 rank all cse get filled.

All the best
