Hello. Have fun in orientation. It's those time for bonding, and make sure you make the most out of it as I reckon you'll be sticking with your group mates most of the time after that.

Have you considered any volunteer works which might help you on your way towards becoming a doctor?? It'd be lovely if you could shadow a few doctors and see what they do every day, too. However, volunteering sounds much of a better choice as you will be studying medicine for the rest of your life and on top of that, it makes you grow as a person. =)
