Be careful what you do. You must know what you want - is it to enhance career prospects, to prepare for life outside or both?
Choose the course and University carefully. There are many easy degrees but they are easy for a reason (i.e. they typically are useful as toilet paper).
If you are still in there are several part time degrees paid for by the military - they normally struggle to get enough people to fill them.
