Have you asked your UAS Sqn Cdr? If the reason for reaching your current stage of flying is due to the time needed to read for a high quality degree, make that point and then propose what you think would be the best way to proceed, if that is a possibility open to you.
Personally I would try to get through IOT as a priority, then do your EFTS. You will certainly get some credit for your previous flying; however, after a couple of hours of refresher work you'd probably be expected to carry on from the point you left off. You will also be better paid once you graduate from IOT, whereas between University and IOT you are no longer an undergraduate, so I've no idea whether you'd be paid anything.
However, there may be some overall policy for people in your situation; again ask your QFI and/or boss for guidance.
Good luck at IOT; I understand that there are different fitness levels for ladies, but I may be out of date on that score.
