Your grade point average is one of the few numbers that follows you from one institution to the next. But GPA means different things in different places: a weighted 5.0 scale in one high school, an unweighted 4.0 scale in another, percentage-based systems abroad, and course-by-course conversions in university admissions. Misreading the scale is where most confusion starts.
This blog explains how GPA is actually calculated, how colleges and universities weigh it in admissions, and what strategies genuinely move the number over time. Whether you are a student planning courses, a parent comparing schools, or an admissions reader, these guides give you the mechanics and the context.
The scale you use changes the meaning of the number. A weighted 4.5 might reflect advanced coursework, while an unweighted 3.7 could be a stronger transcript at a school with no honours classes. Colleges know this, which is why they read GPA in the context of the courses you took. The articles below explain the mechanics of each scale and how to think about your GPA the way admissions teams do.
