You have to just fill out their application form which is available on the Burdwan Raj College site (just search in Google by college name you will get the site). Then you are going to be shortlisted by your number and mostly all the shortlisted candidates may have a minimum 75% result in their hs( including reservation candidates). And you must have a good number in computer science (if you are in 12th)or in mathematics like more than 90%.
