GPA considerations for graduate school applications vary by institution, with most schools placing greater emphasis on the last two years of coursework. While overall GPA is important, a strong performance in senior-level courses can sometimes mitigate earlier poor grades. In Canada, many physics graduate programs require a minimum B+ average over four years for admission. Students transitioning from other fields, such as business, may wonder how their previous grades will impact their applications; typically, schools focus more on grades from the relevant degree. Additionally, incoming first-year students are advised to consider the implications of using AP credits to exempt themselves from courses, as maintaining good grades in all subjects, including electives, may still be necessary for a competitive GPA.
