IBCC Equivalence Calculator (O & A Level)

This IBCC equivalence calculator converts Cambridge (or Edexcel) O Level and A Level grades into the marks the Inter Boards Coordination Commission (IBCC) uses on its equivalence certificate. Pakistani universities, medical colleges and engineering universities use those marks in place of Matric (SSC) and FSc (HSSC) marks, so you need this figure for the NUST, FAST, COMSATS, UET and MDCAT aggregates. Choose O Level for the SSC equivalence or A Level for the HSSC equivalence, enter your grades and the calculator shows the marks for each subject, the total and the equivalent marks out of 900 or 1,100.

IBCC gives each grade a fixed Pakistani mark: A = 85, B = 75, C = 65, D = 55 and E = 45. On the 9–1 scale, 8 = 87, 7 = 82, 6 = 77, 5 = 70, 4 = 60, 3 = 50 and 2 = 40. F, G and grade 1 are not counted. An A* (or a 9) is worth more than 90 and is set subject by subject for each exam session. For O Levels in 2026 it is 94 in Physics, Chemistry, Biology, Computer Studies, Mathematics, Islamiyat, Pakistan Studies and other electives, and 93 in English and Urdu. For A Levels in 2026 it is 95 in Physics, 94 in Chemistry, Biology, Mathematics and other subjects, and 93 in Computer Studies. The calculator uses the published tables for 2024, 2025 and 2026, and 90 for older sessions.

The SSC equivalence uses eight O Level subjects for Pakistani students who sit the exams in Pakistan: English, Urdu, Islamiyat, Pakistan Studies, Mathematics and three electives. IBCC adds the marks and scales the total from 800 to 900, as in its own worked example (750 / 800 × 900 = 844). Foreign nationals and students who took the exams abroad use five subjects (English, Mathematics and three electives), scaled from 500 to 900. The HSSC equivalence adds three A Level subjects to the O Level subjects, so it is out of 1,100 for Pakistani students (8 + 3 subjects) and scaled from 800 to 1,100 for foreign and overseas students (5 + 3 subjects).

Worked example (2026 session, Pakistani student): English A (85), Urdu A* (93), Islamiyat A* (94), Pakistan Studies A (85), Mathematics A* (94), Physics A* (94), Chemistry A (85) and Biology B (75) add up to 705 out of 800. The SSC equivalent is 705 / 800 × 900 = 793 out of 900, or 88.1%. If the same student then gets A in Physics (85), B in Chemistry (75) and A* in Mathematics (94) at A Level, the HSSC equivalent is 959 out of 1,100, or 87.2%.

This is an estimate. IBCC's certificate is the official figure, and it can differ if your subjects, session or nationality category differ from what you enter. Students who are still awaiting A Level results usually apply to universities with their O Level equivalence; check each university's rule, for example NUST and UET use the O Level equivalence with the entry test for A Level students whose results are awaited.
