IBCC turns each O or A level grade into fixed Pakistani marks out of 100: A is 85, B 75, C 65, D 55 and E 45. An A* is worth more than 90, and the exact figure depends on the subject and the year you sat it, for example 94 for O level Mathematics in 2026 and 95 for A level Physics. The marks are then added and scaled. In IBCC's published examples, 8 O level subjects give your Matric (SSC) equivalence, and those 8 plus 3 A level subjects, out of 1100, give your FSc (HSSC) equivalence.
Choose O level or A level, then enter each subject's grade and exam session. The calculator applies the right A* figure for every subject and session and shows the marks under each row.
IBCC grade to marks table
From IBCC's conversion for equivalence page. The same marks apply at O level and A level.
| O or A level grade | Pakistani marks out of 100 |
|---|---|
| A* | Above 90 (subject-wise, see below) |
| A | 85 |
| B | 75 |
| C | 65 |
| D | 55 |
| E | 45 |
| Numeric grade (9 to 1) | Pakistani marks out of 100 |
|---|---|
| 9 | Above 90 (as A*) |
| 8 | 87 |
| 7 | 82 |
| 6 | 77 |
| 5 | 70 |
| 4 | 60 |
| 3 | 50 |
| 2 | 40 |
Grades F, G and U, and numeric grade 1, are not accepted for equivalence. IGCSE numeric grades have their own scale, so an 8 is 87 and a 4 is 60.
A* marks by subject: O level
IBCC publishes a separate A* figure for each examination session. Use the session in which you sat each paper.
| Subject | 2026 | 2025 | 2024 | 2023 | 2022 | 2021 |
|---|---|---|---|---|---|---|
| Physics | 94 | 94 | 94 | 94 | 95 | 94 |
| Chemistry | 94 | 94 | 94 | 94 | 95 | 94 |
| Biology | 94 | 94 | 94 | 94 | 95 | 94 |
| Computer Science | 94 | 94 | 94 | 94 | 96 | 94 |
| Mathematics | 94 | 94 | 94 | 95 | 95 | 95 |
| English | 93 | 93 | 93 | 94 | 95 | 93 |
| Urdu | 93 | 93 | 93 | 93 | 95 | 93 |
| Pakistan Studies | 94 | 93 | 93 | 94 | 95 | 93 |
| Islamiyat | 94 | 94 | 94 | 95 | 95 | 94 |
| Other elective | 94 | 94 | 94 | 94 | 95 | 94 |
These are the figures for Pakistani marks out of 100. The 2022 session was the most generous, with Computer Science at 96.
A* marks by subject: A level
| Subject | 2026 | 2025 | 2024 | 2023 | 2022 | 2021 |
|---|---|---|---|---|---|---|
| Physics | 95 | 95 | 95 | 95 | 95 | 93 |

| Other elective | 94 | 94 | 94 | 94 | 95 | 93 |
English, Urdu, Pakistan Studies and Islamiyat are marked NA at A level, since they are counted at O level. Any A level subject not listed takes the other elective figure.
How IBCC calculates equivalence
IBCC's own worked examples show the method.
O level to Matric. Eight subjects for students who sat in Pakistan: English, Urdu, Islamiyat, Pakistan Studies, Mathematics and three electives. In IBCC's example every grade is A*, giving 750 out of 800. IBCC then scales this: 750 ÷ 800 × 900 = 844 out of 900. Students who sat abroad need five subjects (English, Mathematics and three electives).
A level to FSc. The 8 O level subjects and 3 A level subjects are added, 100 marks each, so the total is out of 1100. IBCC's example totals 1030, which is 1030 out of 1100. For students abroad, 5 O level and 3 A level subjects give a total out of 800, scaled to 1100: 750 ÷ 800 × 1100 = 1031.
So your A level equivalence includes your O level marks. A weak O level result pulls down your FSc equivalence too. See the O level and A level pages for worked examples.
Applying to IBCC
IBCC's FAQs list these charges per certificate: Rs 4,000 for local qualifications, Rs 6,000 for foreign qualifications and Rs 12,000 for an urgent O or A level certificate. Processing takes 15 to 20 working days. Apply for your O level equivalence first; universities ask for both.
Most admissions use the IBCC figure in place of Matric and FSc marks. MDCAT merit, for example, gives 10% weight to SSC and 40% to HSSC, so your equivalence goes straight into the MDCAT aggregate.
For a grade on a Pakistani board result card, the board grade calculator turns marks into the board's grade and percentage.
Recent IBCC notices. IBCC issued a notice on 18 February 2026 about calculating A level equivalence based on the compulsory O level subjects, and an Equivalence Grading 2026 notice on 28 July 2026. The subject-wise 2026 A* figures used here come from IBCC's own tables. Treat every figure here as an estimate: the marks on your IBCC certificate are the final word.
Questions people ask
How many marks does IBCC give for an A* grade?
From the 2021 session onwards, A* is above 90 and IBCC fixes the figure per subject each year. For 2026 O level it is 94 for most subjects and 93 for English and Urdu. For 2026 A level it is 95 for Physics, 93 for Computer Studies and 94 for most others.
Why do some calculators show a different equivalence?
Many calculators count every A* as 90 and scale to 1050 or 1100 without saying why. IBCC's A* figure is higher and changes by session, so those calculators undercount strong students. This calculator uses IBCC's session tables and its own worked examples.
Is the O level equivalence out of 900 or 1100?
IBCC's O level worked example scales to 900 (750 out of 800 becomes 844 out of 900). The percentage, 93.75% in that example, is identical either way, and admissions use the percentage.
Does IBCC accept grade U or E?
E is accepted and counts as 45 marks. F, G and U are not applicable for IBCC equivalence, and IBCC requires at least an E in the three A level subjects for your group. If you have a U, you will need to resit that subject or replace it with another.
Can I use IGCSE numeric grades (9 to 1)?
Yes. IBCC converts 9 as above 90 (like A*), 8 as 87, 7 as 82, 6 as 77, 5 as 70, 4 as 60, 3 as 50 and 2 as 40. Grade 1 is not accepted. Pick the numeric grade in the calculator's grade list.
