Hi Vaibhav,
First of all, you must have either a national rank below 30K or Uttrakhand domicile for GBPUAT because 85% of the total seats are reserved for Uttrakhand candidates, so to secure a seat a domicile is must . Apart from it, you can apply online for counselling, it's usually held by the end of July on the basis of your state rank (if you have a domicile) and the preferences filled you'll get a branch there are 2 online counselling rounds. After each round candidate are asked to report, if one fails to do so the seat is considered to be empty, however, there is a special 3rd round which is offline . It is known as spot round everyone has to report at the university along with their JEE Mains Paper 1 rank, according to your ranks you'll get a branch.
Best of luck.
