Hi anju,

It is not guaranteed that successful verification of documents at one college of university of delhi means that the other college will also approve your documents. For example, if you are taking an hons course and mathematics is a mandatory subject for enrollment in that course than few colleges might count mathematics in your best four and the others might only need it as a subject in your 10+2.

So, everytime you change a college you need to get your documents verified.

Good Luck
