Hi Javier!
Welcome to the forums!
Wow... Medical school or flight school... that's a tough one!
Congrats on your future training date! If you have any questions prior to starting... feel free to let me know. In the meantime... don't forget to be studying now for your written's if you can. Getting your PPL written done in advance is a great idea and if you can hack it... I'd get your IFR and II writtens done to. They are from the same study bank so you can take both tests within 5 minutes of each other.
Flight school may not be as hard as medical school... but it can get intense at times. So... it's best to be as prepared as you can be. Basically... what I'm trying to say is... Study, Study, Study!
Welcome again, and let me know if I can help along the way,
Bob
