Thanks for the input so far. I figured that Mac would be my best chance, if I can do very well on CARS and CASPer. Interesting to know that Queens and UWO could at least be remote possibilities though, depending on the MCAT, based on how they handle GPA. Even if the law marks aren't factored into the GPA calcs I'd imagine it's still incredibly rare for anybody with a UG cGPA or B2/L2 GPA around 3.75 to get into any of these three schools.
I think it would probably be prudent for me to contact all three of those schools to clarify how they would handle the degrees and GPA.
