Every year, thousands of students lose their shot at MBBS not in the exam hall but in the arithmetic afterwards — because they apply the wrong weightage or misread their percentages. Since PMDC standardised medical admissions, one formula dominates public-sector merit lists. Here is the correct MDCAT aggregate formula for 2026, exactly how it is calculated, and a worked example.

The PMDC 10-40-50 Weightage

The standard public-sector scheme weights Matric at 10%, FSc at 40% and MDCAT at 50%. Yes — matriculation still counts, despite the persistent rumour that it has been dropped: it simply carries the smallest share. Your entry test alone is half of your merit score, which is why one extra percentage point in MDCAT moves your aggregate five times as much as one point in matric (0.5 points versus 0.1). Note that schemes can differ — NUMS, army medical colleges and some private universities publish their own weightages — so always confirm the scheme in the admission advertisement before you calculate.

Common Mistakes That Sink Merit Positions

Four errors appear every admission season. First, students add raw marks instead of percentages — 950 out of 1100 is not 950 points, it is 86.36%. Second, they enter the MDCAT score out of 1100-style totals instead of dividing by the 200-mark scale. Third, they assume matric has been removed and skip the 10% component entirely, which understates their own aggregate. Fourth, they copy a friend's weightage from another university's scheme. Each mistake can shift the result by several percentage points — enough to move you across a closing merit list.

The Formula

Aggregate = (Matric % × 0.10) + (FSc % × 0.40) + (MDCAT % × 0.50). Each exam is first converted to a percentage, multiplied by its weight, and the three contributions are added — the result always lands on a 0–100 scale. Two practical points: use your FSc percentage combining Part I and Part II as printed on your board result, and remember MDCAT is out of 200 marks, so divide your score by two to get the percentage (168/200 = 84%).

Worked Example

Suppose Fatima scored 950/1100 in matric (86.36%), 980/1100 in FSc (89.09%) and 168/200 in MDCAT (84%). Her aggregate is (86.36 × 0.10) + (89.09 × 0.40) + (84 × 0.50) = 8.64 + 35.64 + 42 = 86.27%. Notice the split: FSc contributes about 35.6 points and MDCAT 42 points, while matric adds only 8.6 — even though her matric percentage is high. That is exactly how the weightage is designed to work.

What This Means for Your Preparation

Because MDCAT carries half the total, test preparation gives the biggest return: every percentage point gained in MDCAT lifts your aggregate by half a point, while the same gain in FSc adds 0.4 and in matric just 0.1. That said, FSc is the second-biggest lever, so Part II improvement still matters — and a strong FSc percentage also feeds your board position independently. Balance your remaining months accordingly rather than treating MDCAT as the only exam that exists.

Calculate Yours in Seconds

The free MDCAT aggregate calculator on DigitalKasur applies the PMDC 10-40-50 scheme by default, shows each exam's contribution to your final merit, and includes a custom mode for NUMS and private weightages. Need to convert obtained marks into percentages first — 950 out of 1100, or a subject-wise weighted result? The marks percentage calculator handles single subjects and multi-subject aggregates with the working shown.

Conclusion

Remember the structure — 10% matric, 40% FSc, 50% MDCAT — convert each score to a percentage, multiply, add, and compare against the closing merits of previous sessions.
