Hey Hardik,
Congrats on your result. I'm sorry to say, even with ECA quota which allows 5% reservation, you won't be able to get in the colleges of North Campus as they require the best four percentage too be 96 and above even in their last cutoff. E.g Hansraj college had a cutoff of 96% for B.Sc Maths last year. Please look for colleges in south campus or a private University.
Hope this helps, all the best.
