Pakistan's IBCC uses a specific marks-based conversion for O Level and A Level grades. Here is the complete official mapping with grade points, percentage equivalents, and GPA values.
| O Level Grade | IBCC Marks | % Equivalent | CGPA (4.0) | Descriptor |
|---|---|---|---|---|
| A* | 90 | 90% | 3.60 | Outstanding |
| A | 80 | 80% | 3.20 | Excellent |
| B | 70 | 70% | 2.80 | Very Good |

| U | 0 | 0% | 0.00 | Ungraded / Fail |
Source: IBCC Pakistan Official Grade Conversion Table. CGPA = (IBCC Marks / 100) × 4. The IBCC percentage for your overall O Level result = average of marks for all subjects.
| A Level Grade | IBCC Marks | % Equiv. | CGPA (4.0) | Descriptor |
|---|---|---|---|---|
| A* | 95 | 95% | 3.80 | Outstanding |
| A | 85 | 85% | 3.40 | Excellent |

| U | 0 | 0% | 0.00 | Ungraded / Fail |
A Level grades use a slightly higher marks scale than O Level — A*=95 vs A*=90 for O Level. The A Level IBCC percentage is used as the Intermediate equivalent for Pakistani university merit formulae.

Understanding how IBCC converts your O Level grades to a percentage equivalent is essential for Pakistani university applications. Here is the complete, accurate explanation.
The Inter Board Committee of Chairmen (IBCC) is Pakistan's official body for equivalency certificates for O Level and A Level students. IBCC converts Cambridge grades to percentage marks as follows:
This calculator provides an estimate of your IBCC percentage based on the standard IBCC grade-to-marks table. However, IBCC's actual conversion may vary slightly based on the specific syllabus code, the Cambridge session, and whether you appeared through a Pakistani or international centre. The official figure that universities accept is the percentage printed on your official IBCC equivalence certificate — not a calculated estimate.
Get your IBCC certificate early: Apply at ibcc.edu.pk as soon as your Cambridge results are available. Processing typically takes 4–8 weeks. Many universities require the original IBCC certificate at the time of merit list verification — without it, your O Level grades will not be accepted for merit calculation regardless of how strong they are.
Choose "O Level Grades" tab if you are converting Cambridge O Level (IGCSE) results — these form the Matric equivalent in Pakistani university merit. Choose "A Level Grades" if you are converting Cambridge A Level results — these form the Intermediate equivalent. For complete Pakistani university merit calculation, you ideally need both O Level (for Matric %) and A Level (for Inter %) entered separately, then combined with your entry test score using the university's merit formula.
Type your subject name (optional) and select your Cambridge grade (A*, A, B, C, D, E, or U) from the dropdown for each subject. Add all subjects from your O Level results statement. For Pakistani university merit, you typically need to enter at least your best 5 subjects (matching what IBCC counts). If you took 8 or more subjects, enter all of them — the calculator will compute your average across all entered subjects, which is how IBCC typically processes the result.
After entering all subjects and grades, click "Convert to CGPA" to get: your CGPA on the 4.0 scale, your IBCC percentage equivalent, your US-equivalent GPA (for international applications), subject-wise breakdown, and university admission eligibility for major Pakistani institutions. The results also include which entry tests you need to appear in to be eligible for specific programs.
Use this calculator's IBCC percentage estimate for planning purposes. For the official figure, apply for your IBCC equivalence certificate at ibcc.edu.pk as soon as your Cambridge results are published. When applying to Pakistani universities: register for the relevant entry tests (NUST NET, ECAT for engineering, MDCAT for medicine, or institution-specific tests), submit your IBCC equivalence certificate with your application, and track merit lists carefully — cutoffs change each year.
O Level students often underestimate their options or over-rely on a single university. Apply to multiple universities simultaneously — public (NUST, UET, COMSATS) and private (LUMS, FAST, IBA). Private universities often have holistic admissions that better recognise O Level performance, essays, and interview skills — qualities that the FSc/entry-test system doesn't fully capture. LUMS in particular actively recruits O Level students and its LCAT test is designed to assess aptitude rather than FSc syllabus knowledge. Register early for multiple entry tests: NET (for NUST), LCAT/SAT (for LUMS), NU Test (for FAST), and ECAT (for UET and public engineering universities in Punjab).
| University | Min O Level (IBCC %) | Entry Test | Additional |
|---|---|---|---|
| NUST | 60%+ (IBCC) | NET (mandatory) | A Level or FSc for Inter equivalent |
| LUMS | 65%+ (IBCC) | LCAT or SAT | Essays + Interview; A Level preferred |
| UET Lahore | 60%+ (IBCC) | ECAT (Punjab) | A Level Pre-Engineering mandatory |
| FAST-NUCES | 50%+ (IBCC) | NU Entry Test | Maths-heavy entry test |
| IBA Karachi | 60%+ (IBCC) | IBA Aptitude Test | Strong essay/interview component |
| COMSATS | 50%+ (IBCC) | CET / NTS NAT | IBCC certificate mandatory |
| Bahria / Air Univ. | 50%+ (IBCC) | BUET / AUAT | IBCC certificate mandatory |
