What Is GPA and Why Is It Important?

Your GPA, or Grade Point Average, is a single number showing your overall high school academic performance. Each grade you earn is assigned a point value, and those points are averaged across all your classes to reflect how well you’ve performed over time.

Colleges, scholarship programs, and academic opportunities often use GPA as one of the first ways to evaluate applicants. It gives them a consistent measure to compare students from different schools with varying grading systems.

A report by the National Association for College Admission Counseling (NACAC) found that grades in all courses and grades in college prep courses are among the top five factors in admission decisions. This highlights just how much weight academic performance carries in the application process.

Test scores, extracurriculars, recommendation letters, volunteer work, and personal essays also play a role, but GPA is one of the few measures used to evaluate every applicant. A study from the University of Chicago (UChicago) even confirms that your high school GPA is five times stronger than your ACT score at predicting college graduation, which goes to show just how much your day-to-day effort in high school can shape your future success in college.

Beyond admissions, your high school GPA can affect eligibility for honors programs like the National Honor Society (NHS) and determine participation in certain extracurricular activities or sports that require students to maintain a minimum GPA.

Types of GPAs

Now that you know what GPA is and why it matters, it’s important to understand that not all GPAs are calculated the same way. The type of GPA you report can significantly affect the number you present to colleges, scholarships, or academic programs.

Unweighted GPA is the traditional calculation. Each class is worth the same, regardless of difficulty, and grades are converted to a standard 4.0 scale. For example, an A is worth 4.0, a B is worth 3.0, and so on. This method is still the most common in high schools.

Meanwhile, weighted GPA adds value to more challenging courses, such as International Baccalaureate (IB) or Advanced Placement (AP) classes. On a weighted scale, straight As in regular classes equal a 4.0 GPA, but straight As in all AP classes could be a 5.0. In this system, a B in an AP course could be worth 4.0, which is the same as an A in a regular class. This approach rewards students for taking more rigorous coursework.

You may also encounter semester (or trimester) GPAs and cumulative GPAs. A semester GPA reflects your grades for a specific term, while a cumulative GPA averages all your high school grades. Colleges generally focus on your cumulative GPA because it provides a complete picture of your academic performance over time, along with your transcript.

What Is a Good GPA in High School?

A “good” high school GPA ultimately depends on the type of colleges you’re aiming for.

For example, competitive schools like the Ivy League are known for their high academic standards. At Harvard, 72.41% of accepted students in the latest admissions cycle had a 4.0 GPA, and 22.20% had a GPA of 3.75 or higher. In short, getting into these schools requires near-perfect grades and a challenging course load, including AP, IB, or honors classes.

On the other hand, some state universities and less selective institutions may admit students with lower GPAs, especially if they have strong test scores, compelling essays, or other standout qualities.

That’s why it’s important to research the average GPAs of admitted students at your target schools. This will give you a clearer picture of what’s competitive and help you set realistic academic goals.

Average high school GPA

Knowing the national average high school GPA can also help you understand how your grades stack up against those of other students.

A 2023 report from ACT found that the average GPA has climbed steadily over the past decade, with the biggest jump happening in the last five years. In 2021, the average high school GPA reached 3.39. More students are earning higher grades, which can raise expectations for what’s considered competitive at many colleges.

Let’s look at the table below to see how the national average has changed over time:

If your GPA is higher than 3.39, you’re already above the national average and in a stronger position for many college applications. That said, “good” can mean different things depending on the school.

Some competitive schools, like the Ivies, expect a GPA well above this benchmark, while others may consider applicants with GPAs closer to the national average. Again, always check the GPA expectations for your target colleges so you know exactly where you stand.

How to Calculate Your High School GPA

There’s more than one way to calculate your high school GPA. Here’s how to calculate each GPA type:

Unweighted GPA

The basic GPA calculation assumes all classes carry the same weight and each letter grade is worth a number from 0 to 4.

1. Assign each grade a number. 

Use the table to match each grade to its point value (A = 4.0, B = 3.0, etc.).

For example, if you earned an A in English, a B in Math, a C in Science, an A in History, a B in Art, and an A in PE, your numbers would be: 4.0, 3.0, 2.0, 4.0, 3.0, 4.0.

2. Add the numbers. 

Add all the point values together to get a total.

4.0 + 3.0 + 2.0 + 4.0 + 3.0 + 4.0 = 20.0.

3. Divide by the number of classes. 

Take the total and divide it by the number of classes you completed. For example, if you took six graded classes, divide the total by six.

20.0 ÷ 6 classes = 3.33.

4. Record your GPA. 

Your unweighted GPA would be 3.33.

Weighted GPA

A weighted GPA assigns higher point values to AP, advanced, or honors classes. In these cases, the points are slightly higher than those for regular, unweighted courses.

1. Assign each grade a number.

Use the weighted GPA table for AP, advanced, or honors classes. Match each grade to its point value (for example, an A in an AP class = 5.0).

For example, if you earned an A in AP English (5.0), a B in AP Math (4.0), an A in Honors Science (4.5), a B in regular History (3.0), and an A in regular Art (4.0), your numbers would be: 5.0, 4.0, 4.5, 3.0, 4.0.

2. Add the numbers together.

Add all the point values from your classes, then divide the total by the number of classes you took. For example, if you took five classes, divide the total by five.

5.0 + 4.0 + 4.5 + 3.0 + 4.0 = 20.5. Then divide 20.5 by 5 classes = 4.1.

3. Record your weighted GPA.

Your weighted GPA would be 4.1.

Semester GPA

A semester GPA only includes the grades you earned during that specific semester. Any grades from previous semesters are not included.

Use the point tables above to figure out your GPA for the current semester. Here’s how to do it:

1. Calculate your GPA for each quarter. 

Use the weighted or unweighted method described earlier to calculate your GPA for each quarter in the semester.

For example, in the first quarter, you took five classes and earned four A’s (4.0 each) and one B (3.0). That’s (4 + 4 + 4 + 4 + 3) = 19 points. Divide by 5 classes = 3.8 GPA for Quarter 1.

In the second quarter, you had three A’s and two B’s, so (4 + 4 + 4 + 3 + 3) = 18 points. Divide by 5 = 3.6 GPA for Quarter 2.

2. Add both quarter GPAs. 

Add your Quarter 1 GPA to your Quarter 2 GPA.

3.8 + 3.6 = 7.4

3. Divide by two.

Since a semester has two quarters, divide the total from Step 2 by 2.

7.4 ÷ 2 = 3.7 Semester GPA

4. Record your semester GPA.

This number is your semester GPA. It will be either weighted or unweighted depending on the method you used in Step 1.

In this example, your 3.7 GPA is the semester average for your grades in that specific term. If you use this same method for AP or honors classes with the weighted chart, the GPA might be higher.

Cumulative GPA

Your cumulative GPA is the overall average of all your semester grades in high school up to the point you calculate it. For example, if you’re a senior, it would include the fall and spring semester grades from all four years.

Use the point tables above to figure out your GPA for each semester, then follow these steps:

1. Gather your semester GPAs.

Collect the GPA for each semester you’ve completed. Most schools have a fall and a spring semester each year.

Let’s say over two years (four semesters), your GPAs were: 3.7, 3.8, 3.6, and 3.9.

2. Add them together. 

Add all your semester GPAs to get a total.

3.7 + 3.8 + 3.6 + 3.9 = 15.0

3. Divide by the number of semesters. 

Take the total from Step 2 and divide it by how many semesters you’ve completed.
15.0 ÷ 4 = 3.75 cumulative GPA

4. Record your cumulative GPA.

This number is your cumulative GPA. Colleges often focus on this GPA because it reflects your overall academic performance.

In this case, your 3.75 GPA is the average across all semesters completed so far.

How to Improve Your High School GPA

If your grades aren’t where you want them to be, don’t get discouraged. Improving your GPA takes steady effort, determination, and a clear strategy, but with the right mindset, it’s totally possible.

1. Set realistic goals.

Start by looking at your current grades and how far along you are in high school.

If you’re in your freshman or sophomore year, you still have a lot of time to improve your GPA since fewer grades have been recorded. In junior year, you have less time, and by senior year, your options are more limited.

If you’re close to applying to college and still not happy with your GPA, it might help more to focus on raising your SAT or ACT scores or crafting well-written supplemental essays.

You should also figure out your strengths and weaknesses. Check if your grades are going up or down, see which subjects are harder for you, and note which ones you do well in. Think about any activities or personal challenges that may have affected your grades. This information will help you make a plan, adjust your classes if needed, and use your time and energy wisely.

2. Take advanced classes.

One way to boost your GPA is to take more challenging courses when you can. AP, IB, and honors classes are worth more on a weighted GPA scale, so an “A” in one of these classes counts for more than an “A” in a regular class.

However, only take advanced courses if you’re confident you can keep up with the workload. These classes move faster and often require more homework and study time.

That’s why it’s really important to know your own strengths and weaknesses. If you excel in a subject, an advanced class could help you earn extra GPA points while showing colleges you can handle rigorous coursework.

3. Stay organized.

Staying organized can make a big difference in keeping your GPA high. Missed deadlines and forgotten assignments can quickly hurt your grades, even if you understand the material.

Use a planner, calendar app, or notebook to track due dates, exams, and projects. Break large tasks into smaller steps and set personal deadlines so you’re not rushing at the last minute. This gives you extra time to review your work and reduces stress during busy weeks.

4. Ask for help when you need it.

If you’re struggling in a specific subject, don’t hesitate to ask for extra help. A private tutor can explain concepts in a way that makes the most sense for you, walk you through practice problems, and give you strategies tailored to your learning style.

You can also join study groups, where you work with your classmates by sharing notes, quizzing each other, and learning different ways to approach the same problem.
