I don't know where you're getting that number from, but premeds currently make up just under 50% of the class. The numbers are posted on the McGill website.
http://www.mcgill.ca/medicine/admissions/criteria/selection/ 80 premeds, 75 university grads from Quebec, 9 international, 9 OOP Canadians, plus up to 2 positions for natives. I do not believe that the current classes have a higher proportion of Med-P students.
Maybe you never took math class but that's less than 50% premeds. Obviously you are not happy with your choice to go to McGill, but if you're going to try to help others with their decisions, stick to the facts and let them decide what will be best for them. By posting things that are so obviously wrong you are discrediting yourself and your advice.
I have spoken to a number of people in 3rd and 4th year med at McGill, and not a single one of them had the complaints you did. You obviously had a bad experience, but don't make it sound like the institution is a horrible place. Not everyone shares your opinion.
People come to these forums because they want advice. While the advice given here should not be taken as fact, people will be swayed by what they read. If you had a bad experience, feel free to post about it, but also provide information about others who have not encountered such problems and are happy. This forum does not get a lot of posters, so right now you are the only one giving advice. You have a responsibility to give an objective and accurate view in your posts, or else to acknowledge and admit that you are not being objective and accurate. I hate to think that anyone would decide on a med school based on what you have written.
You said only 3 people got their first choice specialty, but if the others were applying to very competitive residencies, the first choice match rate would be expected to be low. If they were all trying to match into family med in Kentucky, would they have gotten their first choices? What if they were all applying to Derm at Harvard? The information you posted is not detailed enough to be informative. My guess is that McGill grads aim high, due to the caliber of their institution. Not everyone who aims high will get their first choice.
