Grade Point Average (GPA) is a numerical measure of academic performance calculated by averaging grades across courses. In Canada, GPA systems vary by institution, commonly using either a 4.0 scale (where A=4.0, B=3.0, C=2.0, D=1.0, F=0) or percentage scales. GPA calculations may weight courses differently based on credit hours—a full-year course counts more than a half-year course. GPA serves multiple purposes: tracking student progress, determining academic standing and honours, qualifying for scholarships and awards, and screening for post-secondary admission or graduate programs. While GPA provides standardized comparison, critics note it doesn't capture learning quality, growth, or non-academic achievements. Different grading standards across institutions make GPA comparison imperfect. Students should understand how their institution calculates GPA and what levels are expected for their academic and career goals. Cumulative GPA reflects all courses taken, while term GPA covers a single semester.
