I am a Canadian student, graduated in 2018 with a 3.93 overall GPA (consistent each year) and AMCAS GPA of 4.0. My MCAT is a 512 (129 /124/129/130). I have taken the MCAT multiple times and the sciences have remained strong 129-130, but CARS is always stuck at 124. I applied to the US and Canada and didn't receive any interview invites. My extra currics include lots of research with 1 pub, 1 pending publication, 4 conference presentations with a poster competition win, medical clinic volunteering, club executive, tutoring, intramural sports etc.
At this point, I don't know what to do, I am considering the IMG route - Ireland, Caribbean, or Australia. I feel like my application is good enough for North America but my CARS is holding me back and I don't know how to fix it.
