Hi! Sorry this is really late, but most CEGEPs require a minimum of 75% for chemistry and math TS or SN (SN is preferred). The application process is pretty simple, but for your letter of intent don't forget to include previous volunteering experience as that is what they really look for (so I've been told by my academic advisers). I hear that John Abbott is good, but it's very intense and you don't really have much of life outside of school. I chose Champlain College (which is on the south shore of Montreal) because I've heard some pretty good things and their simulation lab seems pretty good.
