Introduction to Fundamental Concepts of Chemistry sits in the official PMDC Chemistry curriculum, the document that defines what can and cannot appear in the 2026 paper. Everything on this page is tagged against that curriculum rather than against a chapter list invented for a website, which is why a chapter here matches the chapter your textbook and your teacher use.
Chemistry carries 45 of the 180 questions in the real paper - 25% of your MDCAT score, and the MDCAT is half your merit aggregate. PMDC does not publish how those 45questions are split across chapters, so no honest page can tell you “expect four from Introduction to Fundamental Concepts of Chemistry”. What the archive can tell you is what actually appeared: 3 Introduction to Fundamental Concepts of Chemistry questions out of the 48 Chemistry questions digitised so far.
Work through them with the explanations rather than checking answer letters. The explanation says why the other three options are wrong, and distractors get reused across years far more reliably than whole questions do.
