I got 93.25 (obc) in best 4. Kindly tell the name of college in DU which I can surely take admission after first cut off..

Hello dear aspirant

The college you can take admission in depends on the course you want to pursue,  at this percentage you may not get admission in the campus colleges in the initial cutoff but in the 3rd or 4th cutoff,  you can get into the North campus. The college,  again,  depends on the course.

You can change the college in each cutoff,  there is no restriction on that...
The colleges you can eye on are...
1)  Ramjas college
2)  ARSD college
3)  Shri Venketeshwar college
4)  Kirori Mal college
