??? is this what you're asking???
are your final grades numbers like these? if so, i think there are instructions with the amcas application. if not, your school is probably in the amcas system, and amcas will automatically convert the grades.
at least that is typically how it would be done. i have no idea about your particular school or how amcas does it (e.g. perhaps, an 85 is a 3.2 -- don't know for sure). i'm pretty sure there's a section about it in the instructions. my school's system was very straightforward, so i didn't read the instructions too well.
I go to a Canadian School too (UBC) and 85 is an A and 80 is an A-. On UBC transcripts, we get a percentage and a letter grade...and last year AMCAS used the letter grades exactly as they were on the transcript.
at my JC a B+ is 3.5, anyone else have a system like this cause at most schools i know a b+ is 3.3 but since my JC dosent have A-,B- etc. thats how they do it. anyone else
