I also accepted Western over UofT! I was hesitant about the change in curriculum but I talked to some students who just finished first year and they said that the problems were largely in first semester. They also mentioned that the administration was very willing to hear feedback and they are hopeful that the incoming students will have a much more positive experience
I think regardless of which school you go to, the class that has to deal with the change in the curriculum gets the short end of the stick and then the following year is better (this was also the experience of a friend when her class dealt with the change in the uoft curriculum a few years ago).
Also, I’ve heard that the first two years of pre-clerkship and how much you end up learning/ retaining is largely up to you and what you make of it - so regardless of which school you go to you will have the resources to succeed
Lastly, I also echo previous comments that mentioned how important it is to really consider what you value and making sure that you are close to network of social support! No matter where you decide to go, you will be able to be successful! Congrats on all of the offers, that’s an incredible accomplishment!
