Rice is a great choice if you are interested in med school and also if you are not, but please realize that your interests may change!!! You may decide you like research better, or genetics, or philosophy or something else. Rice will prepare you well for any of these things. You may even decide to take a gap year or two (work as an EMT? Lab tech? who knows????) before med school, should you still choose to go. Relax and think about where you want to be for the next 4 years, and be open to the possibilities that will come from those experiences.
Med school is a ways down the road.....
