Hello.

It depends on your ranking if you can get into your desired college or not. The rank vs marks keeps changing each year due to several factors like difficulty of the paper, number of students attempting the exam etc. It's not possible to predict an exact score, however a score of 140/ a rank of atleast 3000 will get you a seat in most of the colleges.

Good luck!
