Weighted vs Unweighted GPA: What’s the Difference?

Both are your grade point average, but they treat hard classes differently:

• Unweighted GPA uses the standard 4.0 scale for every class. An A is a 4.0 whether it’s in AP Calculus or study hall.
• Weighted GPA gives extra points for harder courses, usually Honors, AP, IB or dual-enrollment classes. An A in an AP class might count as 5.0.

That’s why you’ll sometimes hear about students with a “4.3 GPA”. That number is weighted, because an unweighted GPA can’t go above 4.0.

The standard scales

Important: schools don’t all use the same system. Some add +0.5 for both Honors and AP. Some only weight AP. Some cap the weighted GPA, and some give no extra weight for D or F grades. Your school’s handbook or counselor has the exact rules.

Worked example

Here’s one semester with five classes:

• Unweighted GPA: 18.0 ÷ 5 = 3.60
• Weighted GPA: 19.5 ÷ 5 = 3.90

If your classes have different credit values, multiply each grade point by the class’s credits, add them up, and divide by the total credits. Our GPA calculator handles credits for you, and our guide on how to calculate GPA walks through it step by step.

Which one do colleges look at?

Both, in a way. Many US colleges look at your transcript as a whole, not only one number. Admissions officers see which classes you took and the grades you earned in each.

• Many colleges recalculate GPAs using their own method so they can compare students from different high schools fairly. Some strip out the weighting, and some only count core academic subjects.
• Course rigor matters. A 3.7 unweighted GPA with several AP classes often looks stronger than a 4.0 with no challenging courses.
• Scholarships often set a minimum GPA, so check whether they mean weighted or unweighted.

Should you take the harder class?

It’s a common question. Is it better to get a B in AP or an A in a regular class?

• On a weighted scale, a B in AP (4.0) equals an A in a regular class (4.0).
• On an unweighted scale, the A wins (4.0 vs 3.0).
• In admissions, the AP class often counts for more, because it shows you challenged yourself. That only holds if you can keep your grades solid across all your classes.

A good rule of thumb is to take the hardest classes you can do well in without burning out. Five APs with straight C’s is worse than three APs with A’s and B’s.

Outside the US?

Most UK, Canadian, Australian and international systems don’t use weighted GPA at all. Schools there might use percentages, letter grades, or scales such as UK A-levels, Australia’s ATAR or IB points. If you’re applying to US colleges from abroad, they will look at your grades in the context of your own country’s system. Don’t try to convert your grades into a GPA yourself unless the college asks you to.

FAQs

Can I have a 5.0 GPA? Only on a weighted scale, and only if every class is AP/IB-level and you got straight A’s.

Is weighted GPA always higher? It’s never lower. If you took no Honors or AP classes, your weighted and unweighted GPAs are the same.

Which GPA goes on my resume? Use the one your school reports on your transcript. If you list both, label them clearly, for example “GPA: 3.6 unweighted / 3.9 weighted”.
