Hi,
I would agree with mazzy.
Flying is fun, so any reason to do so is good enough for me.
I would advise to get rid of the theory exams as soon as possible, thus giving you more time to study for the university.
It took me 2 years to complete my PPL, and getting the theory out of the way helped a lot (e.g. go flying when the weather is good, instead of nose in the books).
Don't know if you did so already, but take a trial lesson, this might aid you in your decision as well.
Good luck, and happy landings
Peter
