I have got 93 percent in +2.is there eny chance to get BSc chemistry from north campus university

I assume you are talking about Delhi University. If you are a General category student, you have a chance at colleges like Aurobindo College, Bhaskaracharya college of applied sciences, Sri Venkateshwara college and maybe Deshbandhu college and Daulat Ram in later rounds.
If you are a reserved category student, you can have a chance in Ramjas College and Kirori Mal College in the later rounds.
Good luck.
