Hello,

GBU is Gautam Buddha University which is present in Delhi. So if you want to take admission in biotechnology BTech then you have to give JEE Mains examination. I think you gave this examination that's why you written 48 air or all India rank and 12 is OBC category rank , but you didn't mention this is rank or marks. If it's rank then dear you will get NITs also. So many good government colleges you will get. But if it's marks then it's quite difficult to predict which college you will get. I'll provide you a link below you can check it for more details about the college

All the best.
