I too have bad Cegep grades and would love to not have to submit my Cegep transcripts. This didn't cause you any problems with U.S schools?
Also do you have any experience with OLSAS (ontario law schools)? Is it possible to just not submit your CEGEP grades to OLSAS and move forward with Ontario applications. It's bad enough that according to OLSAS and my schools grading scale A+ becomes 4.0 and A becomes 3.7. Why not make A+ 4.0 and leave A a 4.0, most of my teachers state openly they never under any circumstances give an A+. bah!
