How this was worked out: Every MCQ in the 11 solved ETEA MDCAT papers we hold (2005 to 2023) was matched to the chapter it tests, which is how the share column is worked out. These are counts of real questions from real ETEA MDCAT (Khyber Pakhtunkhwa) papers, not an opinion about which chapters matter. The MCQ column then applies each chapter's share to the 45 Chemistry MCQs the current ETEA MDCAT pattern carries, rather than averaging the raw counts: those older papers were set to different totals, and a number taken straight off them would describe a paper nobody is sitting any more.
