Which program is better to choose keeping the fact that you want to get into the medical school afterwards? And in Mcmaster university, I saw theres something called health sciences which require more than 90% average in 6 U courses in grade 12. What's so special about it?

Health science is THE program you want to go to if you want to go to medical school after and McMaster is the place to go for health science. A 90% alone i don't think would get you in, should get like 92-93 plus imo and also have sum great extra curricular activities. However I think once you get above the cut off they start viewing your application form. At my school my friend with a 94 got in because he had a spectacular form but two students with a 97 and 95 did not because of their forms. Now those two are amazing at English as well so you just got to make it better than just amazing. Also, the positions you hold are pretty important my friend that got in, was the school president and will probably be valedictorian. However to get into med school, you can go to Western biomed and also life science at UFT- St. George and McMaster life science. I hear york has some good science programs too so you can get into med school straight from there and it might be a bit easier at york. hope that helps
