Are you saying that your parents won't pay ANYTHING towards college? If so, then you're going to have very few choices since you would need a total free ride (and would still probably have to take some small loans).
If your parents will pay for some college, how much will they pay?
Does your transcript say a 3.5 weighted GPA for grades 9-11?
There are some schools that would give your full tuition or somewhat less, but you'd still have room, board, books, fees to pay for.
Since your goal is med school, are you set on that major?
