Here's one way of looking at it: If your parents will support you in getting a college education and only require that you attend two meetings a week and one morning of Field Circus, do the math. 6 hours of your time per week in exchange for room and board and (possibly) tuition & transportation assistance is a huge bargain if you're just looking at the finances.
The other side of the coin is your sanity, which only you can answer.
Whatever decisions you make, take your time and look at the big picture.
All the best,
