Hello dear aspirant

Hope you’re doing well.

If you are getting any seat in any college in the first cut off list released by DU, it is also advised to take admission and book your seat to be on the safer side.

If by luck, you get a better college in the 2nd cut off list, you can withdraw admission from the first college and submit documents in another college.

Hope this helps.
please ask if you have any more questions.

All the best for your future!!
