How many MDCAT marks do I need?
Enter your Matric and FSc marks and the aggregate you are aiming for. This works out the MDCAT score that gets you there, using the official PMDC formula - 10% Matric + 40% FSc + 50% MDCAT. Everything runs in your browser, so nothing you type is sent anywhere.
The arithmetic, in the open
Your Matric and FSc percentages are already decided, so their weighted contribution is a fixed number. Subtract it from your target and you have the number of points the MDCAT still has to supply; divide by the MDCAT's 50% weight to turn that back into a percentage, then into marks.
locked in = (Matric % × 0.1) + (FSc % × 0.4) MDCAT % = (target − locked in) ÷ 0.5 marks = MDCAT % ÷ 100 × 180 (rounded up)
Marks are rounded up, because a fractional mark does not exist and rounding down would quietly tell you that you had cleared a threshold you had missed. The whole point of this page is that the number is the one you can rely on, so it errs upward.
Why this number moves more than any other
Matric is 10% and finished. FSc is 40% and, for most candidates reading this, also finished. The MDCAT is 50% - more than the two of them together - and it is the only component still in play. That asymmetry is why a candidate with mediocre academics can still reach a good college and why a candidate with excellent academics can still miss one.
One practical consequence of the 180-question, no-negative-marking format: every blank is a mark you have chosen not to try for. Work the ladder in the table above and you will usually find the gap between two targets is a handful of questions, not a different person.
