I see your point about 3 being FT studies for most schools but I'm guessing due to law school being "more difficult" than your standard undergrad program they want to see that students can handle a higher course load while maintaining good grades? That's just my guess though.
I wouldn't assume you aren't going to get in this year. Do you have any connection to the Maritimes or Sask? Any special considerations? EC's? It's so hard to say 100% and I am around the same stats as you and I feel like I am on that borderline point as well.
I used 7Sage for about 1 month half-heartedly (working 3 jobs while studying) and managed a 5 point increase from Nov to Jan. I really enjoyed the curriculum and feel like I retained way more information than during my few months of self-study. I know if I don't get in this cycle I would probably re-subscribe to them for a longer period and dedicate more time to studying and expect another few point increase.
