Arpit, it seems really difficult for you to get CSE branch in PES University. The branch closes in 850-900 rank in the second round, which is the final round.

Depending on your rank, you might have a chance of getting EC branch.

Other than that, you can definitely get all the other branches which includes EE, Civil, Mechanical, BioTech etc. But it depends on the number of students who appeared for the exam and as well as the difficulty of the paper.

Feel free to ask if you have any more queries.

Hope this helps!

All the best!
