Why no 2020 or 2021? Those years' MDCAT was run by PMC rather than UHS, and we couldn't find a complete, reliable copy of either paper — so we don't publish a guessed version.
197 of 200 questions — why?
197 of 200 questions available. Q2 is left out because the correct answer (virion) is not an option and UHS removed it from marking; Q11 prints the correct option twice; Q110's diagram options are missing from our source.

How we mark these papers
When the official key is wrong, we say so.
Every answer here is checked against the official key published for that paper. Where the key and the subject disagree — and on some papers that happens dozens of times — we mark the answer the science supports, and the explanation on that question says plainly that we have departed from the key and why. One paper's published key turned out to belong to a different paper code entirely.
Where a question cannot be resolved at all — an unreadable scan, a missing diagram, an option the original paper never printed — we switch it off rather than guess, and the paper's own note tells you how many are missing and which. That is why a paper can read 218 of 220 instead of a tidy 100%: the number is the truth about the paper, not a target.
