Frequently Asked Questions

What's the difference between weighted and unweighted GPA? ▼

Unweighted GPA uses a standard 4.0 scale for every class (A=4.0, regardless of difficulty). Weighted GPA adds extra points for harder classes: typically +0.5 for Honors and +1.0 for AP/IB, so an A in an AP class counts as 5.0 instead of 4.0.

How do I calculate my GPA by hand? ▼

Convert each letter grade to grade points (A=4, A-=3.7, B+=3.3, B=3.0, etc.), multiply by the course's credit hours, add a weight bonus if applicable, sum all the results, then divide by your total credit hours.

What is a good GPA? ▼

A 3.0 unweighted GPA is generally considered solid (B average). A 3.5+ is competitive for most four-year colleges, and 3.8+ unweighted (or 4.2+ weighted) is typical for highly selective schools.

How high school GPA is calculated

Each letter grade is converted to grade points, multiplied by the course credits, and the total is divided by the total credits:

GPA = Σ (grade points × credits) ÷ Σ credits.

On the standard unweighted scale an A is 4.0, an A− 3.7, a B+ 3.3, a B 3.0 and so on down to an F at 0. For a weighted GPA this calculator adds 0.5 point for honors classes and 1.0 point for AP or IB classes, so an A in an AP class counts as 5.0.

Example

Course	Level	Grade	Unweighted	Weighted
AP Biology	AP	A	4.0	5.0
English	Honors	B+	3.3	3.8
Algebra II	Regular	A−	3.7	3.7
Spanish	Regular	B	3.0	3.0

With one credit each, the unweighted GPA is 14.0 ÷ 4 = 3.50 and the weighted GPA is 15.5 ÷ 4 = 3.88.

Weighted versus unweighted

Schools do not all weight the same way. Some add a full point for honors, some cap weighted GPAs, and some do not use plus and minus grades. Many colleges recalculate GPA with their own method, often using only core academic courses, so treat any weighted number as specific to your school. Read weighted vs. unweighted GPA explained for how admissions offices read both.

Raising your GPA

Courses with more credits move the average more, so prioritize them.
The more credits you already have, the smaller the effect of each new grade, which is why early semesters matter.
Retaking a course helps only if your school replaces or averages the grade; policies differ.
