Grade Scale Reference
Understand different grading systems and customize your grade scale. Adjust the point values below to match your specific school's policy.
Pass/Fail grades
P (Pass) and NP (Not Pass) grades are excluded from GPA calculations by default.
Understanding Plus/Minus Grading
Grading scales are not federally standardized in the United States. Many colleges and high schools use plus/minus grading to provide more granular grade distinctions. This system rewards students who are close to the next letter grade. For example, an 89% B+ is mathematically worth more (usually 3.3) than an 81% B- (usually 2.7).
However, some districts use a flat scale where an 89% and an 81% both equal a flat 3.0. By adjusting the values in the editor above, you ensure all calculators across GPAtally use your exact local rules. If your school uses a flat scale, simply change the B+ and B- values to equal 3.0.
Example of Scale Differences
Consider a student who earns exactly an 88% in three different classes. Their final GPA depends entirely on the school's scale:
- School 1 (Strict Flat Scale): 88% falls into the 'B' bracket. Grade = 3.0.
- School 2 (Standard Plus/Minus): 88% falls into the 'B+' bracket. Grade = 3.3.
- School 3 (Generous Plus/Minus): 88% falls into an 'A-' bracket at this specific school. Grade = 3.7.
This massive discrepancy highlights why it is vital to check your specific student handbook before calculating your GPA.
What This Result Means
When you customize the grade scale above and click save, every calculator on GPAtally will respect those new boundaries. This means your High School GPA Calculator and Semester GPA Calculator will produce mathematically accurate results tailored specifically to your transcript. If you are comparing your GPA against national averages or university standards, remember that admissions officers will standardize your grades to their internal formulas.
Tips for Understanding Grade Scales
- Check the Syllabus: Always read the syllabus on the first day of class. Even within the same university, one professor might make a 90% an A, while another requires a 94%.
- A+ Does Not Equal 4.3: Even if your school offers an A+, it is almost universally capped at a 4.0 on an unweighted scale to prevent artificial inflation.
- Colleges Standardize Scales: Do not stress if your high school grades harshly. Colleges look at your "School Profile" to understand your district's specific scale and evaluate you fairly against others.
- Save Your Scale: Once you find your school's exact decimal values, save them in the editor above so you don't have to re-enter them every time you use a calculator.
Sources and Notes
The default values provided are based on the standard College Board 4.0 scale. Grading policies are decentralized in the US, so your institution's specific numerical cutoffs may differ.
Frequently Asked Questions
How do I edit the grade scale?
Use the Grade Scale Editor above. Change the numerical values next to each letter grade, click "Save", and those custom values will be used automatically across all calculators on GPAtally.
Why do schools use different grading scales?
Different districts adopt scales they believe best reflect student achievement. Some prefer the simplicity of a flat 4.0 scale, while others prefer the precision of plus/minus grading.
Is an A+ worth more than a 4.0?
Usually not. On a standard unweighted scale, an A+ and an A are both worth 4.0. Some specific law school admissions algorithms (like LSAC) award a 4.33 for an A+, but this is rare.
Do international students use a 4.0 scale?
No. Most international systems use completely different metrics (like a 100-point system in India, or a 1-6 scale in Germany). International students must use credential evaluation services to convert to the US 4.0 scale.
Why isn't my GPA exactly a 4.0 if I have a 95% average?
Because GPA is tiered, not linear. You do not simply divide 95 by 25. Every individual class is assigned a letter grade first, and those letters are averaged. A 95% might fall into an A- tier at your school.
Should I convert my 100-point scale before applying to college?
No. Always report your GPA exactly as it appears on your official transcript. Let the college admissions officers perform the mathematical conversion.
