Hello Shivam , first of all i would like of congratulate you for such a good performance.

So as you may know most of the reputed colleges and universities take admissions through their entrance exams so the result of boards will not be that much helpful l. You have to crack their entrance exams.

Even some of the college tale admissions through class 12th results so you admission will also depend on the college you choose because merit of every colleges will be different.

Hope it will help you.
