Hey,

The north campus college of du be the most reputed and well known colleges and demands a high percentage to get in. Your cgpa be very low to get admission on migration as it totally be based on your merit score.  Also it depends on the authorities of the concerned colleges. You may contact the concerned authorities to get a better idea regarding it.
For a student to migrate from one college to another, he/she will need to have a written permit that the principals of both the colleges agree on the matter.
Migration is not an easy task. If you want to migrate from your college you need to have a strong reason as it is stated in provision that migration is not a right, it is only a permissive facility and not an obligatory one. It all depends upon both incoming and outgoing colleges concerned.
Good luck!
