Teacher Song Peiqi from Dalian pointed out that the GPA requirement of the University of Waterloo for the last two years is above B, that is, 75%, but this is based on Canadian undergraduate graduates. Mainland China will generally get higher grades, so there will be a discount on GPA after coming over. The GPA of American undergraduate graduates is generally higher (the GPA of American universities is generally much higher than that of Canadian universities). In this case, the evaluation Committee will also refer to the average grade point of the applicant's class.
As for English, there is a hard score requirement, as long as it is achieved, and it will not be used much if it is higher. For details, please go to Waterloo, official website.
The University of Waterloo is a very good university in science and computer science. But generally speaking, it is much more difficult for Canadian universities with the same ranking to apply than the United States, and it is even more difficult to ask for scholarships. Why not try America?
