Short answer. GPA is the total grade points of your main subjects divided by their number. For the optional 4th subject, subtract 2.00 from its point and add the rest to the total. The top GPA is 5.00.
How the Bangladesh GPA works
SSC and HSC use a 5.00 scale. Marks map to a letter and a grade point.
| Marks | Grade | Point |
|---|---|---|
| 80-100 | A+ | 5.00 |
| 70-79 | A | 4.00 |
| 60-69 | A- | 3.50 |
| 50-59 | B | 3.00 |
| 40-49 | C | 2.00 |
| 33-39 | D | 1.00 |
| 0-32 | F | 0.00 |
Add the grade points of your main subjects. Divide by the number of main subjects. That is your GPA.
The 4th subject is optional. Its rule is simple. Take the grade point of the 4th subject and subtract 2.00. If the answer is above zero, add it to the total of your main subjects. Then divide by the number of main subjects, not by one more. A 4th subject with 2.00 or less adds nothing, and it cannot lower your GPA.
The GPA cannot go above 5.00. If the sum gives more than 5.00, the result is 5.00.
Main subjects differ by group and level. This tool lets you add or remove rows, so you can match your own list. Do not put the 4th subject in the main list.
An F in a main subject is a failed subject. This tool shows the plain average and warns you. It does not apply any board rule for a fail, so read your board notice for that case.
How to use the result
Pick a grade for each main subject. The point shows next to it. Then pick the 4th subject grade, if you have one. The result shows the GPA with the bonus, and the plain GPA without it, so you can see what the 4th subject adds.
Many universities and the GST admission process use the GPA of SSC and HSC, and some also look at subject grades. Check the rules of the place you apply to. Keep your board marksheet at hand, because it is the official record and can differ from a hand sum.

Worked example
Example. Six main subjects: A+, A+, A, A, A- and B. Points: 5 + 5 + 4 + 4 + 3.5 + 3 = 24.5. Plain GPA: 24.5 / 6 = 4.08.
The 4th subject is an A (4.00). Subtract 2.00 to get 2.00. Add it: 26.5. Divide by 6: 4.42.
Questions
How is the 4th subject counted?
Take its grade point and subtract 2.00. Add the rest, if any, to the total of the main subjects. Do not add it to the count of subjects.
Can the 4th subject lower my GPA?
No. A 4th subject with 2.00 or less adds nothing.
What is the highest GPA?
5.00. A result above 5.00 is capped.
What is the pass mark?
The table here shows 33 marks as a D (1.00). The board sets pass rules for each subject, so read your board notice.
Is the table the same for SSC and HSC?
The grade table is the same in the sources checked. The list of main subjects differs by group and level, so edit the rows to match yours.
