^^ What dr dre said.
Would you still want to do this if you had to pay for it all yourself?
In my experience having parents pay for it all won't be really helping you in the long term. I am eternally grateful that all my flying was paid for myself (and the scholarship I worked bloody hard for) and I don't owe anyone anything.
As for school work, you should always have some back-up qualifications should something horrible happen with your medical.
