Everyone has their own personal reasons for wanting to transfer university, the course you’re currently studying does not match your expectations, home and family situations such as being to far away from home or you could simply not be enjoying the university you are at.
Whatever the reason, a lot of people transfer every year and its not as difficult as you may think. Saying that, there is some effort and time required and there are no guarantees at all that you will even be able to transfer.
It is important from the start to ensure you are making this decision for the right reasons. If you are unhappy with any aspect of your course or university then I would strongly advise talking to your tutors first as they may be able to advise on improvements.
The first important thing you should know is that any enquiry or application to transfer university will not have any negative impact on your current placement at all, so you have nothing to lose.
