Since my cycle is, for the most, part over, I thought I'd post my stats and application results:
cGPA: 3.59 (I calculated it to be 3.60 and thought about following up with OLSAS, but didn't bother in the end)
Been out of school for 5 years - have been working in finance and am actively involved in the community as well.
Accepted: Queens (Jan), Alberta (Feb), Western (Mar), Osgoode (May), UBC (waitlisted initially then accepted in June)
Rejected: Toronto, Ottawa
Waitlisted: UVic (# was in the 40s out of 70 something, so don't think my chances are too good)
Focused my essay on why I want to make a career change and went into depths about my current career & volunteer work, and had my essay read over by many people - you'd be surprised what you hear from them. Find someone who won't be afraid to rip apart your essay - it helps you in the end!
I think my reference letters were pretty average - I had 2 professional and 1 academic letters (totally unnecessary by the way - most schools ask for just two). I was hoping to get away without having an academic letter, because I was afraid none of my professors would remember me and write very mediocre letters. I emailed a few law schools asking if this was okay and their responses all said the same thing - that they'd much prefer to have an academic letter. Ended up looking through my undergrad transcript and picked a few courses that I got the highest mark in in my last year of univ and emailed the profs, and all of them were responsive and more than happy to write a letter for me (and surprisingly remembered me although I think I was pretty quiet in most of my classes).
I wasn't sure how my cycle would go given my average LSATs and cGPA, but glad I went ahead and applied and spent the amount of time I did on my essays, as I ended up getting into my first choice (Osgoode). Hopefully my info helps other mature students looking to apply out there.
