Most Repeated ETEA MDCAT Chemistry MCQs
Every Chemistry question here appeared in two or more different ETEA MDCAT exam years. There are 20 of them across the 37 solved past papers TestUstad holds, and each row names the papers and years it was found in so you can check it yourself. They cluster in Transition Elements, which produces more repeats than any other Chemistry chapter on the paper.
How a repeat is counted
A question counts as repeated only when the same question, with the same correct answer, appears in two or more different exam years. Matching is done on the question text and the correct answer together, so a question that came back with its options reworded or reordered is still caught, while the dozens of unrelated English questions that share a stem like “Choose the correct option” are not counted as repeats of each other.
Measured across 37 solved past papers, 2005 to 2025, 6,760 questions searched, from the ETEA MDCAT, MDCAT, NUMS papers TestUstad holds solved. Nothing on this page is predicted, padded or inferred. Every row names the exact papers and years it was found in, and you can open those papers here and check.
What that measurement actually found: 20 repeated questions, and the most any single question has come back is 2 exam years. If you have seen a site claim a ETEA MDCAT question that recurred five or six times, ask which papers it counted. On this corpus that question does not exist, and saying so is more useful to you than inventing one.

Chemistry chapters these repeats come from
Revise these chapters first. A chapter that has produced a repeat before is one the examiner returns to, whether or not the same question comes back.
Most repeated ETEA MDCAT Chemistry MCQs: frequently asked questions
How many Chemistry MCQs have actually repeated in ETEA MDCAT?
20 Chemistry questions have appeared in two or more different exam years across the 37 solved ETEA MDCAT past papers TestUstad holds. The most any one of them has repeated is 2 exam years. Each is listed on this page with the papers and years it was found in.
Which Chemistry chapter produces the most repeated ETEA MDCAT MCQs?
Transition Elements carries the most measured repeats of any Chemistry chapter on the ETEA MDCAT paper. That makes it worth revising regardless of whether these exact questions return, because a chapter that has produced repeats before is a chapter the examiner keeps coming back to.
How is a repeated Chemistry MCQ identified?
By matching the question text together with its correct answer across different exam years. Both halves are needed: matching the full question alone would miss a question that came back with reworded options, and matching the question text alone would wrongly group unrelated questions that share a generic stem. Only genuine cross-year repeats are counted.
Should I only study these repeated Chemistry MCQs for ETEA MDCAT?
No. 20 questions is a revision sweep, not a syllabus, and there is no guarantee any specific question returns. Use this list in your final week to lock in questions that are known to come back, and spend the rest of your time on the chapters that carry the most marks. TestUstad ranks those separately on the ETEA MDCAT most important topics page.
Are answers and explanations for these Chemistry MCQs free?
Yes. Every question here links to its own page showing the correct answer and a written explanation of why that option is correct, free and with no account. TestUstad cannot publish a question without an explanation.
