If your L2 is accurate, you're actually kind of okay and can get away with a score in the mid 160ish. UofA, UCalgary, USask (and others; I can't remember all of them) are all B2 schools. You'll have more difficulty with CGPA schools without a 170+.
Thank you! My only thing with this is that I would have to manually calculate an average based off the threads, each year for each school I’m interested in. If the data is not already accessible online somewhere this is what I’ll have to do!
