Hi
You are sort of in the same boat as me, i could go to college or start my training, i am planning to go to the USA when i am 18, this is after 2 year college course!
The way i look at it is that your still young, so think about doing your 4 year degree, then you would start your training at about 25, you have the rest of your life to be a pilot!, if it was me, i would do the degree, then go for training...
Hope this Helps
Jay
