Im 16. I'm just starting grade 11 and am in the best possible place right now to start preparing for university, but i have no idea who to talk to about this.. I either want to go into buisness or medicine, most likely medicine. I have looked at apprenticeship programs but these seem to only apply if you want to go into the trades. Any advice on who i should talk to? Just need guidance on what options actually apply to me right now, or insight on who i can talk to to help me start getting ready.
