加拿大b-是多少分？
谢邀~ 加拿大的成绩评估体系里，平时的成绩（GPA）不是唯一的标准，还有O-level/High School Diploma的考试成绩和Bachlors最后两年平均的成绩来衡量申请者的本科成绩。一般认为，如果Bacherlor最后两年的GPA能达到80+（满分100），那么通常就已经达到申请研究生的水准了；如果目标是Top Meng，那GPA至少要在85+。
以UW的MENG为例，官网显示的要求是Applicants should have a strong background in mathematics and the quantitative sciences (students whose major is not quantitative are encouraged to take extra math or stats courses). GPA is generally considered to be around 3.7 out of a possible 4.3 undergrad GPA. A lower GPA may still be considered if the applicant has other qualifications such as high level AP/IB coursework completed， or exceptional performance on standardized tests (GRE/GMAT).
当然这个只是最低要求，想要得到理想学校的offer，还是尽量把GPA保持在高的水平。
