Frequently Asked Questions
Common questions about GPA and grading calculations.
How do I calculate weighted GPA?
To calculate weighted GPA, assign point values to your grades based on course difficulty. Regular classes usually use a 4.0 scale. Honors courses add +0.5 (e.g., A=4.5), and AP/IB courses add +1.0 (e.g., A=5.0). Our Gradebook Calculator handles this automatically when you select the course type.
Is a 3.7 GPA good in college?
Yes, a 3.7 GPA is generally considered “Magna Cum Laude” or “High Distinction” at many universities. It indicates a mix of A’s and A-‘s. Use our tool to see how future semesters can impact your cumulative score.
How to convert percentage to letter grade?
Typically, 90-100% is an A, 80-89% is a B, etc. However, many schools use +/- systems (e.g., 90-92% is an A-). Our calculator uses the standard college grading scale displayed below in the “How it Works” section.
How our Gradebook Calculator works
1. Percentage to Grade Scale
When you use “Points” or “Percent” mode, we convert your score to a letter grade using this standard scale:
| Score % | Grade | Score % | Grade |
|---|---|---|---|
| 97 – 100 | A+ | 77 – 79 | C+ |
| 93 – 96 | A | 73 – 76 | C |
| 90 – 92 | A- | 70 – 72 | C- |
| 87 – 89 | B+ | 60 – 69 | D |
| 83 – 86 | B | 0 – 59 | F |
2. Gradebook Point Scale
The calculator then converts letter grades into GPA points:
| Grade | Points | Grade | Points |
|---|---|---|---|
| A+ / A | 4.0 | C+ | 2.3 |
| A- | 3.7 | C | 2.0 |
| B+ | 3.3 | D | 1.0 |
| B | 3.0 | F | 0.0 |
