Common grading terms explained
These are the core terms you will meet when calculating academic scores.
| Term | Meaning |
|---|---|
| GPA | Grade Point Average for a single term, on a fixed scale such as 4.0 or 10.0. |
| CGPA | Cumulative GPA averaged across all completed semesters or years. |
| Credit hours | The weight assigned to a course, usually based on contact or study time. |

Because grading scales and admissions formulas differ by institution and country, always confirm the exact scale or conversion your school or test board uses before relying on a result.
How do I choose the right tool?
Match the tool to what you need to find out:
- One term or semester only? Use the GPA Calculator with each course’s grade points and credit hours.
- Overall average across every completed semester? Use the CGPA Calculator to combine all courses into one cumulative figure.
- Wondering what you need on an upcoming final? Use the Final Grade Calculator with your current grade, the final’s weight and your target.
- Marked a test of correct answers out of a total? Use the Test Grade Calculator for the percentage and letter grade.
- Course mixing assignments, quizzes and exams? Use the Weighted Grade Calculator to apply each component’s weight.
- Prepping for college admissions? Use the SAT Score Calculator or the ACT Score Calculator to estimate your scaled total.
- Need a percentage from a GPA for an application or transcript? Use the GPA to Percentage Calculator.
A common workflow tracks each term with the GPA Calculator, rolls terms together in the CGPA Calculator, then converts with the GPA to Percentage Calculator when an application asks for a percent.
Why use Toolzent’s education & scores tools?
Toolzent’s education and scores tools are 100% free with no sign-up and nothing to install. They run privately in your browser, so the grades you type stay on your device, and return instant results. As a worked example, three courses graded A, B and A worth 4, 3 and 3 credit hours give grade points of 4.0, 3.0 and 4.0, so the GPA is (16 plus 9 plus 12) divided by 10, which equals 3.7. Every tool is mobile-friendly and pairs accurate formulas with clear examples.
