Introduction: GPA and College Admissions
The grades you earn in high school are one of the most important factors colleges consider when evaluating your college applications. Most of the time, this is done by considering your Grade Point Average (GPA), and colleges use GPA to assess your academic performance over time. Some may even set minimum GPA requirements for admission or scholarships. However, not all GPAs are calculated the same way. In fact, the GPA on your high school transcript may look very different from the GPA a college calculates when reviewing your application.
As someone who has worked with students from over 100 high schools in 15 states, I've seen a lot of GPA calculations. Different high schools use different grading scales, weight systems, and cumulative averages, which can make understanding your "real" GPA confusing. Because colleges receive applications from students from around the world, they often recalculate using their own GPA formula to help standardize their review process. I recalculate my clients High School GPA on several different scales to help manage their college expectations and make their journey to college as transparent as possible.
How High Schools Calculate GPA
There is no single, universal way to calculate GPA. Some high schools use a numeric average, while others use a 4.0 scale. Some high schools add weight to grades for Honors, Advanced Placement (AP), International Baccalaureate (IB), or Dual Enrollment (DE) courses, while others assign quality points instead. Some schools even exclude non-academic courses like PE and electives from their GPA calculations. Below are the most common GPA calculation methods, and many high schools include several of these GPAs on their transcripts:
1. Numeric Average GPA
Some high schools report GPA as a simple numeric average—meaning they add up all of the final grades earned in every class and divide by the total number of classes. In this system, a 95 might appear to be a 3.7, but that's not always the case when converted to a traditional 4.0 scale.
2. Grade Point Average (GPA) on a 4.0 Scale
Many schools and colleges use a 4.0 scale:
A = 4.0
B = 3.0
C = 2.0
D(if passing at your school) = 1.0
F = 0.0
To calculate your GPA, you assign the corresponding number to each letter grade and add all those numbers together. Then, you divide that total by the total number of classes taken. See the case study below.
3. Academic vs. Cumulative GPA
Some high schools report a cumulative GPA that includes ALL courses, including PE, band, and art, which often inflates the GPA because students tend to score higher in non-academic courses.
Some colleges recalculate GPAs using only core academic courses: English, Math, Science, Social Studies, and World Language.
4. Weighted vs. Unweighted GPA
Weighted GPA: Some schools increase the value of Honors, AP, IB, or DE courses. For example, an A in an Honors course might be worth 4.5 instead of 4.0, and an AP/IB/DE class might be worth 5.0 instead of 4.0.
Unweighted GPA: This uses a standard 4.0 scale, where an A is always worth 4.0, regardless of course difficulty.
5. Other Factors in GPA Calculations
Some high schools use plus/minus systems (e.g., an A- is a 3.7 instead of a 4.0).
Some high schools include middle school grades on the transcript but not in the GPA calculation.
How Colleges Recalculate GPA
While some colleges will take the GPA as posted on your transcript, many colleges recalculate the GPA using an academic core GPA. That means they will take the grades you earned in high school in English, Math, Science, Social Studies, and World Language courses and convert them to a 4.0 scale. Depending on the school, some will add quality points to honors, AP, IB, and DE courses. It's always good to ask how colleges recalculate GPA so you can more accurately understand where you fall compared to their average. I've heard of some colleges adding 0.5 to honors courses and 1.0 to AP/IB/DE. Some colleges will just count the number of A's, B's, and C's you've earned; others will only consider grades earned in 10th and 11th grade.
One of the most common is how the University of Georgia recalculates GPA.
First, UGA only considers grades earned in academic courses taken while in high school. If you took high school courses in middle school (like Spanish), those grades do NOT go into your GPA calculation.
UGA then looks at the unweighted grade earned in each course. For example, if you attend a Fulton or Gwinnett County school, they will remove the 7 or 10 points from the grades added to your advanced coursework before converting each grade to a 4.0 scale.
To standardize the process and to ensure that rigor is accounted for, UGA then adds 1.0 quality point for each AP/IB grade earned (e.g., a B in AP US History is equal to a 4.0 instead of 3.0)
While UGA counts DE in their rigor calculation, they do NOT add quality points to DE grades when recalculating the UGA GPA.
Finally, UGA adds up all the points and divides by the total number of grades.
While UGA's mid-50% GPA for Fall 2024 was 4.09-4.33, they also state that 91% of their core grades are A's, and 8+% are B's.
Case Study: A Closer Look at GPA Calculation
Let's examine a fictional student to see how their GPA shifts based on different calculations.
Meet Anthony, a high school rising senior.
Anthony attends a high school that adds 7 points to all Honors, AP, and DE courses. Here's a look at Anthony's transcript:
Course Name | Grade w/ 7 Points | Weighted GPA | Grade w/o 7 Points | Unweighted GPA | UGA GPA | |
9th | ||||||
AP Gov | 96 | 4 | 89 | 3 | 4 | |
Algebra 1 | 99 | 4 | 99 | 4 | 4 | |
Honors English | 98 | 4 | 91 | 4 | 4 | |
Spanish 2 | 95 | 4 | 95 | 4 | 4 | |
Band | 100 | 99 | 4 | |||
Honors Biology | 96 | 4 | 89 | 3 | 3 | |

Geometry | 97 | 4 | 97 | 4 | 4 | |
Chemistry | 92 | 4 | 92 | 4 | 4 | |
Spanish 3 H | 95 | 4 | 88 | 3 | 3 | |

AP Lang | 84 | 3 | 77 | 2 | 3 | |
AP US History | 96 | 4 | 89 | 3 | 4 | |
Honors Anatomy | 96 | 4 | 89 | 3 | 3 | |
Algebra 2 | 97 | 4 | 97 | 4 | 4 | |
Weight Training | 100 | 100 | ||||

95.55555 | 3.857142 | 92 | 3.33333333 | 3.571428571 |
What Does This Mean for Anthony?
With weighting, Anthony's GPA appears to be a 95.5 cumulative average, which might be mistaken for a 4.0, but it is really a 3.857.
Without weighting, Anthony's GPA is closer to a 3.3 on a 4.0 scale, significantly lower than expected.
For UGA, which uses the unweighted grades before adding 1.0 back to the AP courses, he has a 3.57.
Depending on the college recalculations, Anthony's GPA could vary even more!
Why Understanding GPA Calculation Matters
Since colleges use different methods to recalculate GPAs, students, and families must understand how GPA works at the colleges on their radar to have an accurate idea about their admissions chances.
Remember:
Your high school GPA might not match what a college sees.
Academic courses matter more than electives.
Honors weighting varies by school and may be removed by colleges.
At the end of the day, colleges care most about the actual grades earned in academic courses. So, rather than focusing solely on boosting a weighted GPA, students should take rigorous coursework in which they can succeed and earn the highest grades possible.
What This Means for Your College Strategy
Every college evaluates GPA differently, and understanding how your student's academic record will be assessed is critical for making informed decisions about course selection, college lists, and scholarship eligibility.
