well, at UofT most profs. normally turn 89's into 90's ... so you get either 88 or 90.
Anyway, I think its fair. GPA, like I said, awards consistancy, and if you view it in that light, it gives an accurate picture of a student's record. Also, some schools use 4.3 and 4.0 scales, but these GPA are easily converted. If you apply to a school that uses a 4.3 scale, from a school that uses a 4.0 scale, the 4.3 scaled school will obviously convert your GPA. You can't compare the two ... it makes no sense at all.
