Please also note that you need to make sure of your scoring system. For this CGPA calculator to work for you, even on a 5.0 scale, the following have to apply.
The table below should be clear for you to comprehend. It's a designation table for the scores, grade points and grades used by most schools. Others might differ but never in calculation.
| Total score(100%) | Grade | Grade Point(GP) |
| 100 - 70 | A | 5.00 |
| 69 - 60 | B | 4.00 |
| 59 - 50 | C | 3.00 |
| 49 - 45 | D | 2.00 |
| 44 - 0 | F | 0.00 |
We had to clarify this because we understand that some schools use grading systems that further break down each division. For example, some schools not only have the A grade, but also the AB or BA grade if you score, say 65. This means that they multiply the unit by 4.5 instead of 4.
If this is the system your university, polytechnic or college adopts, this CGPA calculator will not work for you. Thank you for using this GPA tool. Please don't forget to share it.
