Hello Aayush,

First of all, let me make you clear that UPES has no clear cut off which means that you will not get a particular rank as a cut off for a branch like what happens in JEE MAINS.

Minimum board percentage is required for admission. And then there is a counseling round. When you go for counseling you can pick from the seats that are available. So it really depends on the people who are getting counseled before you. The person having a better rank get to chose the branch of his choice. So that is how it is done.

Hope this helps.
