I have lots of friends that transfer from diploma to degree course. If its in the same university, that would not be a problem. Its a good move to switch to degree. I think there is a limit on how many credits you can transfer, correct me if i am wrong.

If you do that, then you will start 2nd year in degree already lo. Then with credit transfers, that certainly can help a lot . Anyway, I feel that taking up a degree is good. All the best
