🎒 High School GPA Calculation Explained

Your high school GPA is one of the most critical numbers in the college admissions process — it summarizes four years of academic performance into a single figure that admissions officers compare across thousands of applicants. Keeping an accurate, up-to-date picture of where you stand helps you set realistic targets for the schools on your list.

This calculator tracks your performance across AP, Honors, and standard courses, and reports your GPA on both weighted and unweighted scales. Add each class with its grade and course type, and the tool handles the rigor bonuses and averaging automatically.

⚖️ Weighted vs. Unweighted GPA

An unweighted GPA uses the plain 4.0 scale regardless of course difficulty — an A is 4.0 and a B is 3.0 whether the class is a standard elective or the hardest AP on offer. It measures pure grade performance without accounting for rigor.

A weighted GPA grants bonus points for challenging coursework: AP/IB classes are effectively graded on a 5.0 scale (+1.0 bonus) and Honors classes on a 4.5 scale (+0.5 bonus). This is why competitive students taking rigorous schedules can report GPAs above 4.0, and why many colleges recalculate both versions when reviewing applications.
