Hey

Your best of four is pretty good. But this year, there is a huge rise in the cut offs especially for popular courses including Political science. Since, you are from OBC category and looking for college in North campus, then estimation can be made that you may get a college here in closing cut offs.

It's better you secure a seat in other college so that when further cut offs are released, you can change college as per your preference.

You can predict colleges here -

Thanks and good luck
