✅ Weighted and Unweighted GPA

The most difficult part about calculating your current GPA is the difference between weighted and unweighted courses.

How to know if your school gives extra points for certain classes? How to transform your letter grade into a percentage if the course is weighted? Are there any advantages of taking AP or Honors classes?

In this chapter, we’ll answer all these questions. Just keep reading!

Unweighted GPA

Usually, you get letter grades for passed courses throughout the year. There’s nothing difficult in converting those letters into a percentage (read the next chapter to figure out how exactly) until there are weighted courses.

To know your GPA, you have to find your result on a GPA scale where the highest grade equals 4.0. This task isn’t challenging at all. You just have to find a 4.0 scale—read further to see it in chapter III.

With unweighted GPA system, there are possibilities of having a regular letter grading or one with pluses and minuses. In this case, every letter with plus or minus has its own GPA values, except for A and A+ that both equals 4.0.

Weighted GPA

This is where everything becomes more complicated, but we’re here to help!

In many schools, there are classes with higher standards. They are usually called AP (Advanced Placement) programs. Their mission is to give more information than regular courses do and prepare you for a college. These classes also are a great chance to earn points in your future college while you’re still a high-school student.

AP’s are usually scored on a scale of 1.0 to 5.0 but can also be higher, depending on your school’s decision.

Why take those courses? The entire period that you spend in high school, you’re fighting for the place in a college. The majority of colleges appreciate it when you take challenges during your studies. Even if you get B, it still shows you as a dedicated student, and, by the way, when converted into GPA, AP’s B equals 4.0, which is A or A+ in your regular courses. It also introduces you to the college program, and you may try out your skills and learn your weaknesses.

Along with regular and AP classes, there are also Honors ones. Their scores are more challenging to achieve, that’s why they usually are estimated 0.5 higher than regular courses. For example, if you get B- it equals 2.7 for regular courses and 3.2 for Honors courses.

When computing your GPA, be careful to use the calculator that suits your requirements, in other words, if you’re a student who attends AP or Honors classes and wants to know the exact GPA, use only those calculators that consider weighted courses.

In conclusion, we must say: you don’t have to attend every weighted class. It’s still important to gain as high grades as you can during regular classes, prepare for SAT, and participate in clubs and scholarships.

☝️ How to calculate GPA?

There are several excellent tools for GPA calculating online. Using one of them is the best way to figure out all you want to know in a short period.

Don’t always have access to the internet? Then, we’ll teach you to calculate GPA without any tools.

This chapter is a detailed guide on how to do it on a piece of paper with the help of the formula and a couple of tables.

Step 1

Fill in this table based on the information your school gives. Be accurate when filling in your class types as they determine how high your letter grades are. Also, notice that credit hours may be different for two courses.

Course Letter Grade Credit Hours Class type
History A 3 Regular
Literature B 3 Regular
English B+ 4 Honors
Biology A- 4 AP
Math A+ 3 AP

Step 2

After that, use the following table to convert letter grades into a percentage. Make sure to take GPA score appropriate to your class type: Regular, Honors, or AP.

Letter Grade Regular Honors AP
A+ 4.0 4.5 5.0
A 4.0 4.5 5.0
A- 3.7 4.2 4.7
B+ 3.3 3.8 4.3
B 3.0 3.5 4.0
B- 2.7 3.2 3.7
C+ 2.3 2.8 3.3
C 2.0 2.5 3.0
C- 1.7 2.3 2.7
D+ 1.3 1.8 2.3
D 1.0 1.5 2.0
F 0.0 0.5 1.0

There’s also the scale for those who gain grades in percentage.

Percent Grade GPA Honors AP
97-100 4.0 4.5 5.0
93-96 4.0 4.5 5.0
90-92 3.7 4.2 4.7
87-89 3.3 3.8 4.3
83-86 3.0 3.5 4.0
80-82 2.7 3.2 3.7
77-79 2.3 2.8 3.3
73-76 2.0 2.5 3.0
70-72 1.7 2.3 2.7
67-69 1.3 1.8 2.3
65-66 1.0 1.5 2.0
0-65 0.0 0.5 1.0

Step 3

Write down the GPA score you got and multiply it by credit hours for every course. Also, determine the total credit hours during your semester.

Course Letter Grade Credit Hours Class type Grade Points
History A (4.0) 3 Regular 3 x 4.0 = 12.0
Literature B (3.0) 3 Regular 3 x 3.0 = 9.0
English B+ (3.8) 4 Honors 4 x 3.8 = 15.2
Biology A- (4.7) 4 AP 4 x 4.7 = 18.8
Math A+ (5.0) 3 AP 3 x 5.0 = 15.0
Total 3 + 3 + 4 + 4 + 3 = 17 12.0 + 9.0 + 15.2 + 18.8 + 15.0 = 70

Step 4

Divide the number of grade points by the average of credit hours:
70/17 = 4.11
In our example, 4.11 is the student’s GPA.

Step 5

Many students have been asking about the overall GPA formula.

To figure out cumulative GPA, you need to know every semester’s GPA and total grade points. To know grade points, you should simply multiply GPA by credit hours. After that, divide the total number of grade points by the sum of credit hours:

Semester GPA Credit Hours Grade Points
1 3.5 13 3.5 x 13 = 45.5
2 3.7 14 3.7 x 14 = 51.8
3 5.0 14 4.0 x 14 = 56
4 4.6 12 4.6 x 12 = 55.2
Total 13 + 14 + 14 + 12 = 53 208.5

Grade Points sum / Credit Hours sum = Overall GPA
208.5/53 = 3.9

These were guidelines on how to calculate high-school GPA on a weighted scale (5.0) or unweighted scale (4.0). If you still have any questions, feel free to ask them in comments!

☝️ How to raise GPA?

This chapter is the last part of our guide but may be the most significant.

Once you figure out your GPA, you may want to make it even higher. That’s why we’ve collected some pretty helpful tips to show you the right direction.


1. Balance

The most common problem students may have with GPA is when they start putting efforts only during the last weeks. This attitude projects on all of your studies even if you catch up all the material at the end.

So, our tip is to have a nice start and handle your procrastination as soon as possible. Study every day to avoid putting 3-month’s material into the memory in the last week.

2. Structure

Determine the hours at which you’re most productive and include them in your schedule. Stick to the plan. Put all the efforts to follow your schedule.

Organize not only your time but workplace and notes as well. The more structured your learning is, the easier it’s to get higher grades.

3. Revision

Any school program implies daily and weekly revisions of the material you get. Make sure you catch up with understanding and remembering all the significant information.

Every week go through your notes to find out weaknesses and pass a quiz to memorize the topic better.

4. Ask questions

The majority of teachers have office hours when you can discuss some challenging topics with them or ask for help. Don’t be shy to use this opportunity as long as it helps to understand the subject and shows your teacher you care about the studies.

5. Be confident

It may seem boring or uncomfortable to participate in discussions in a class but give it a try. Your teacher wants to know which students care about their grades and make the challenging work to improve.

The only way to show them is to participate in their lessons.

6. Challenge yourself

You will never be fully prepared for difficult courses. So, take on some risks and subscribe to a couple of AP classes!

It’s significant to attend some because any college you’ll apply in future is interested in this aspect of your academic achievements. The higher grades you have for AP classes, the more your GPA and chances to get into a good college are.

7. Learn for tests

GPA isn’t everything. To raise your chances to get into a college of your dreams, you may put a lot of efforts into studying for standardized tests like SAT.

You can find a lot of worksheets and guides online to practice.

8. Choose the place

Feel unfocused and procrastinate a lot? Try to change your studying place. At home or in a dorm you may experience too loud noises and many distractions.

If you study at the library or in an empty class, things are different. You feel more concentrated and can accomplish more tasks at a time.

These were tips on how to raise your GPA, and now you’re definitely ready to know your result. We hope, our guide is helpful to calculate your high-school GPA whether using tools, detailed guidelines, or charts.
