Exam Countdown
Count down to your exams.
Students and teachers can turn marks and grades into meaningful results in seconds. These education tools calculate GPA and CGPA, convert between marks, grades and percentages, and handle the credit-hour weighting that makes an academic average correct rather than a simple mean.
Each tool follows a standard grading scale and lets you add as many subjects as you need, so it works for a single test or a full year across multiple terms. Everything runs in your browser, so your results stay private.
How to use these tools
- Choose your tool: GPA for one term, CGPA to combine terms, or the grade and marks calculators to work from raw scores.
- Add a row for each subject and enter its grade or percentage.
- Enter the credit hours for each subject so the average is weighted correctly rather than treated equally.
- Add as many subjects as your term or year contains — there is no fixed limit.
- Read the overall result, including the letter grade and percentage band, and adjust the grading scale if your institution uses a different one.
Common ways people use them
- Working out your semester GPA the moment your results are published.
- Combining several semesters into a single CGPA for a scholarship or job application.
- Checking whether your current attendance is above the minimum required to sit an exam.
- Converting NEB or college marks into a percentage and grade for a form.
- Helping a class teacher tally marks across subjects and produce a final result quickly.
Good to know
GPA vs CGPA
GPA (Grade Point Average) is usually the average for a single term. CGPA (Cumulative GPA) is the average across all terms combined. Both weight each subject by its credit hours, so a heavier subject counts more toward the final number than a lighter one.
Why credit hours matter
A weighted average multiplies each subject’s grade point by its credit hours, sums those, and divides by the total credit hours. This is why a top grade in a 4-credit subject moves your GPA more than the same grade in a 1-credit subject — a plain average would ignore that difference.
Grades, percentages and bands
Most scales map a percentage range to a letter grade and a grade point (for example an A on a 4.0 scale). The tools show the band each grade covers, and several let you enter a percentage and have the matching grade filled in automatically.

Frequently asked questions
- What grading scale do the GPA tools use?
- They use a standard letter-grade system on a 4.0 grade point scale, with each grade mapped to a percentage band shown on the tool.
- What is the difference between GPA and CGPA?
- GPA is usually the average for one term, while CGPA is the cumulative average across all terms, weighted by credit hours.
- Can I enter a percentage instead of a letter grade?
- Yes. Several tools let you enter a percentage and map it to the matching grade automatically.
- How is a weighted average different from a normal average?
- A weighted average multiplies each subject by its credit hours before averaging, so subjects with more credits count more. A normal average treats every subject equally.
- Can I change the grading scale?
- Yes. The grade calculator uses a configurable scale, so you can match the bands your school, college or board uses.
- How many subjects can I add?
- As many as you need. Add every subject in your term or year, each with its own credit hours.
