I'm in the same position - I love it, and I think that I will be well placed when I'm finished.
Can't really add more to what's been said, other than I'm in the same boat. I'm looking forward to all the milestones.
Started at 14, 15.5 now, solo 16 e.t.c
I do one a month, and have skipped the solo (obviously), and moved on to navigation.
I think it was a wise thing to do - keeps me occupied, whilst spreading out cost (I admit, not incurred on me!) and yet still getting the same end product.
Regarding exams, I've found no trouble fitting in revision for school, and for flying. Exam validity works in my favour.
