Umm... Firstly, you made sense! Secondly, I really would be unsure how to answer this. Personally, if they said they only take the grades recieved at time of admission to calculate a scholarship, then that is probably what they do. However, I know a bunch of other schools that do re-evaluate grades at midterms for higher scholarship amounts, but I don't know about UofT. My best advice: just email the school's Awards and Financial Aid office or the Admissions office (because they are the one's who usually make the offers of admission and scholarship, but this sometimes varies from school to school). They should be able to answer your question, and it never hurts to ask, right? Good luck!
