I've done the whole 'start at 14, solo at 16, PPL at 17' thing. Had a lesson a month up to solo, then a bit more frequently, then some intensive time during my holidays. Passed in minimum hours.
Survived GCSE's pretty well, but it intefered with my A-levels a bit. (AS should I say, Still got another year left!)
It's a much larger commitment than you think. The first 10 hours wont intefere with anything, but then Solo to Skills Test, and all the ground examinations will.
I've no regrets! Just remember to find the time to have some fun as well, but don't let that take over either! Get the balance right!
Oh, And you'll soon find you don't have as much time/money to fly as you would like, but it's great when you do!!
Keep me updated, would like to hear how you're getting on
Put.
