Oh wow, its been a while since i logged in! Just posting my thread from 11 years ago with the same question
https://forums.premed101.com/topic/42422-how-exactly-does-one-get-a-986-two-year-average/?tab=comments#comment-518766
I am a practicing physician now and ended up getting into med after 3 years with a 2 year average of 95+%. There are lots of smart people out there and some of those 97+ averages were obtained by people either going to smaller schools (Athabasca, Lethbridge etc) or had a very generous Master's supervisor. Either way, back in those days there were certainly people that went for the typical phys/pharm major and got in with high 90s averages with just pure work ethic and talent.
None of the stuff I can share on undergrad course selection is probably relevant now so i have no practical advice.
All the best!
