GPA Mechanics
Practice lesson. Nothing here is saved to My Plan.
GPA feels like a mystery number that judges you. It is actually simple arithmetic, and arithmetic can be planned. This lesson shows the machine, then lets you simulate your own comeback.
Before you start: where are you now?
Rate yourself honestly. Nobody sees this but you.
The machine itself
Unweighted GPA: every class converts to points (A=4, B=3, C=2, D=1, F=0), and GPA is the plain average. That is the whole machine. Two things follow: an F hurts twice (zero points AND it drags the average), and the more semesters you have banked, the slower the number moves in either direction.
- Weighted GPA adds bonus points for honors/AP/IB classes (often on a 5.0 scale). A B in an AP class can beat an A in an easy one on the weighted scale.
- Colleges recalculate. Many strip electives and recompute core-only (English, math, science, social studies, language), and some look at 10th-12th only. Translation: your core classes matter most, and 9th grade is not a life sentence.
- Ask about repair options. Grade replacement, credit recovery, and summer retakes exist in many districts. The counselor question: "if I retake a class, what happens to the old grade?"

The big idea
GPA is an average, and averages have momentum: early grades count the same as late ones, but late ones are the only ones you still control. Colleges see trend lines, not just totals. From any starting point, the winning move is identical: make the next semester your best one.
