Weighted vs. Unweighted GPA
If you are a high school student preparing for college, you have probably heard the terms "weighted" and "unweighted" GPA thrown around. But what do they actually mean? More importantly, which one do colleges care about when deciding your admission? In this guide, we will break down the differences between the two grading scales, how AP and IB classes factor in, and how admissions officers actually evaluate your transcript.

What is an Unweighted GPA?
An unweighted GPA is the most traditional way to measure academic performance. It is calculated on a strict 4.0 scale. Under this system, the difficulty of your classes does not matter. An 'A' in an easy elective is worth the exact same amount as an 'A' in Advanced Placement (AP) Calculus.
Because it doesn't account for class difficulty, the unweighted GPA is a pure reflection of your grades. The maximum unweighted GPA you can achieve is a 4.0, which means you got a perfect 'A' in every single class you took.
What is a Weighted GPA?
A weighted GPA is designed to reward students who take challenging courses. Instead of capping out at 4.0, a weighted scale typically goes up to 5.0 (and sometimes 6.0 in some school districts).
Under a weighted system, extra points are added to your grade point for taking advanced classes like AP, IB, or Honors. For example, an 'A' in a regular class is still worth 4.0. But an 'A' in an AP class might be worth 5.0. A 'B' in an AP class would be worth 4.0 (the same as an 'A' in a regular class).
| Class Type | A (90-100%) | B (80-89%) | C (70-79%) |
|---|---|---|---|
| Regular | 4.0 | 3.0 | 2.0 |
| Honors | 4.5 | 3.5 | 2.5 |
| AP / IB | 5.0 | 4.0 | 3.0 |
Because of this scaling, it is possible to have a GPA higher than 4.0. If you want to see how your specific AP and Honors classes affect your average, you can use our high school GPA calculator which features a built-in weighting toggle.
The Core Differences
Unweighted (The 4.0 Scale)
Measures your raw grades without considering course difficulty. It is simple to compare students, but penalizes students who challenge themselves with hard classes and might get a 'B' instead of an 'A'.
Weighted (The 5.0 Scale)
Measures both your grades AND the rigor of your schedule. It rewards students for taking AP and IB classes, but makes it harder to compare students from different schools with different weighting policies.

What Colleges Actually Look At
So, which one matters more? The truth is, colleges look at both.
College admissions officers are experts at reading transcripts. They know that a 3.8 unweighted GPA with 8 AP classes is much more impressive than a 4.0 unweighted GPA with zero AP classes.

1
Unweighted for Comparison: Many top universities actually recalculate every applicant's GPA on an unweighted 4.0 scale. This creates a level playing field, since every high school weights AP classes differently.
-
2
Weighted for Context: They will also look at your weighted GPA to see if you took advantage of the hardest classes available at your school. Colleges want to see that you challenged yourself.
-
3
Class Rank: Many high schools use weighted GPA to determine class rank (Valedictorian, Salutatorian). Colleges care deeply about class rank as it shows how you performed relative to your peers.
The main takeaway: Do not take easy classes just to protect your unweighted 4.0. Colleges would rather see you get a 'B' in an AP class than an 'A' in a regular class. However, if you are struggling and getting 'D's or 'F's in AP classes, it is time to drop down to a regular level, as failing a class severely damages both GPA scales.
Frequently Asked Questions (FAQ)
Do colleges look at weighted or unweighted GPA?
Colleges look at both. Admissions officers often recalculate your unweighted GPA to compare you fairly against students from other schools. However, they also look at your weighted GPA and the rigor of your classes (AP, IB) to see if you challenged yourself.
Is a 4.0 weighted GPA good?
A 4.0 weighted GPA is considered average if your school uses a 5.0 scale for AP classes. It means you likely earned B's in advanced classes or A's in regular classes. To be competitive for top universities, you generally want a weighted GPA above 4.0.
What is the highest unweighted GPA?
The highest possible unweighted GPA is a 4.0. Because the unweighted scale does not give extra points for AP or Honors classes, an A in any class (regular or advanced) is always worth exactly 4.0 points.
