The thing is that I'm pretty sure I'll be going into a medical field even if I decide to stay with bioengineering, but if I decide to stay with engineering, theres much less human contact and if I stay with med school, its much more work, even though its more rewarding.
and my roommate is a pre-dental senior, so he's always at the student doctor forums. I've looked at the site a couple of times before, its pretty informative for premeds.
I've talked to my advisor, who's a MD and electrical and bioengineer, and she basically told me the same thing you guys told me. Just make sure you want to be a doctor before you jump into med school.
