Thanks.
. I completely agree. But will MHS give me a better chance? What if I regret it?
Woah, just re-read what I wrote - hope I don't sound too anti-MHS, I've got anything at all against the school

No school itself will 'give you a better chance'. It really comes down to the opportunities that you have and what you make of them.
Like most schools across the state, either Xavier or MHS will prepare you for a great future no matter what you want to do in life.
Just keep in mind, at the end of the day, it's your decision, not anyone else's. Take a tour of the school during a normal day if you can. Talk to current students who go there. Go where you feel most comfortable and at ease, and where
you think you'll be most prepared for Med.
