I really have no idea ... however, the rumor about things like this is ...Schools don't actually drop anything when they consider you for admission. They look at your whole transcript. However, when they report their median GPA's, they exclude say, their admitted applicants worst year, or whatever they say they do. UofT does this - I would imagine other schools employ the same sort of tactics to stay competitive.
keep in mind this isn't coming from an admissions committee...I'm just repeating what people have told me. Plus, if you read schools admissions policies, few actually say they don't count course credits.I think it's fair though because ...If only one school isn't counting their applicants worst year, and reporting the inflated figure, then it is reasonable for all other schools to do the same. However, they don't want to make admissions decisions based on these number, which is also reasonable.but i take no responsibilty over the truth of the above or previously posted comments. Just a rumor I guess ...but also, how would that effect you? it doesn't. If you are worried about UBC, it doesn't matter, cause they are evaulating ALL of their applicants on the 4 year scale. If they only report a 3 year GPA, then it has no effect on admission decisions.
