Enter your AP and non-AP courses to see exactly how your AP classes affect your weighted GPA. Compare weighted vs unweighted side by side.
Enter your current courses. Mark each as AP, Honors, or Regular — the calculator applies the correct weight automatically.
AP (Advanced Placement) courses receive a +1.0 bonus on the weighted GPA scale. This means an A in an AP class is worth 5.0 instead of the standard 4.0, a B in an AP class is worth 4.0, and a C is worth 3.0. The bonus applies regardless of whether you take the AP exam or what score you receive on it.
The purpose of the weight is to reflect academic rigor — AP courses are college-level, and the grading scale acknowledges that earning a B in AP Chemistry is a stronger academic achievement than earning a B in a standard chemistry course.
| Grade | Regular GPA Points | AP Weighted Points (+1.0) |
|---|---|---|
| A+ / A | 4.0 | 5.0 |
| A− | 3.7 | 4.7 |
| B+ | 3.3 | 4.3 |
| B | 3.0 | 4.0 |
| B− | 2.7 | 3.7 |
| C+ | 2.3 | 3.3 |
| C | 2.0 | 3.0 |
The +1.0 bonus per AP course looks significant, but its impact on your overall weighted GPA depends on how many total courses you take and what grades you earn. Here is what different AP course loads produce when you earn all A's:
| AP Courses (out of 6 total) | Weighted GPA (all A's) | Unweighted GPA |
|---|---|---|
| 0 AP courses | 4.00 | 4.00 |
| 1 AP course | 4.17 | 4.00 |
| 2 AP courses | 4.33 | 4.00 |
| 3 AP courses | 4.50 | 4.00 |
| 4 AP courses | 4.67 | 4.00 |
| 6 AP courses (all) | 5.00 | 4.00 |
Notice that the unweighted GPA stays at 4.0 in every scenario — the AP bonus only affects the weighted number. This is why colleges use both: weighted GPA signals rigor, unweighted GPA provides a standardized baseline for comparison.
No — and this is one of the most common misconceptions about AP courses. A B in an AP class earns 4.0 weighted points, which is the same as an A in a regular class (also 4.0 unweighted). On the weighted scale, a B in AP is neutral compared to an A in regular. On the unweighted scale, a B in AP (3.0) is lower than an A in regular (4.0) — but colleges understand this context.
The practical implication: taking AP courses and earning B's does not hurt your weighted GPA. If you are on the borderline between taking AP and not taking it because you are worried about a B, the weighted GPA math does not justify that concern. The bigger risk is overloading — taking too many AP courses at once and performing poorly across all of them.
Your AP course grade (the letter grade on your transcript) is separate from your AP exam score (1–5, set by College Board). Colleges see both, but they affect different things:
For college credit purposes, a score of 4 or 5 on the AP exam can allow you to skip introductory college courses entirely — saving both time and tuition.
AP courses receive a +1.0 bonus; Honors courses typically receive a +0.5 bonus. For weighted GPA purposes, two AP classes produce a larger weighted bump than four Honors classes (assuming equal grades). However, AP courses also carry higher workload and exam pressure.
