I'm definitely not wiser than FutureDOC haha. One of the smartest premed students I knew went to UQO though and seemed to love it. Just my 2 cents. They rotate their entire 3rd and 4th year in the US right? Have their own hospitals in NOLA right? Con is that I heard it's hella expensive and you're an IMG?
I know what it feels like to feel rushed, but I also don't think you need the masters since you already have one with a 3.9? All Touro's would do is guarantee you an interview at their campus (which you already got?). 3 waitlists (do you know where you're ranked on them?) and I'd say you'd have a solid shot at getting off at least one of them?
When does UQO start? Is there a way you can deposit and maybe wait til the end of this cycle to see if you get pulled off the WL at a DO school? If not... well you'll have to make the decision yourself, there are a lot of factors and I don't know that much about UQO. But I would assume that it's not like a Caribbean school, they have admission stats comparable to some DO/MD med schools (3.4/29) and a 93% match rate in the US last year (I'm sure you've seen the match list, it looks pretty comparable to what I'd imagine most DO schools look like) so personally if you don't want to wait another year of this grinding cycle I'd take that acceptance and attend?
And yeah when did you apply?
