How this was worked out: Every MCQ in the 19 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 81 Biology 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.

ETEA MDCAT Biology most important topics: frequently asked questions
What are the most important Biology topics for ETEA MDCAT 2026?
The highest-value ETEA MDCAT Biology chapters are Biodiversity and Variety of Life (about 18.4 MCQs), Coordination and Control (about 8.3 MCQs), Forms and Functions of Plants (about 6.8 MCQs), Biological Molecules (about 6.3 MCQs) and Cell Structure and Function (about 5.8 MCQs). Together they account for 56 percent of the 81 Biology MCQs on the ETEA MDCAT paper. The ranking comes from counting every Biology MCQ in the 19 solved ETEA MDCAT past papers on TestUstad.
How many Biology MCQs are on the ETEA MDCAT paper?
Biology is worth 81 MCQs on the ETEA MDCAT paper as set by Educational Testing and Evaluation Agency, Khyber Pakhtunkhwa, spread across 21 chapters. This page ranks all 21 of them by how many of those MCQs each chapter is worth.
Where does this ETEA MDCAT Biology ranking come from?
From 19 solved ETEA MDCAT past papers held on TestUstad, covering 2005 to 2023. Every Biology MCQ in them, 1,127 questions in total, is tagged to the chapter it tests, which is where each chapter's share comes from. The expected MCQ counts apply that share to the 81 Biology MCQs the current ETEA MDCAT pattern carries. You can open any of those papers and check.
Should I skip the low-priority Biology chapters for ETEA MDCAT?
No. Every chapter in this table appears on the ETEA MDCAT paper, and ETEA MDCAT is decided by a handful of marks. A chapter marked Standard still costs you the marks you drop on it. Use this ranking to decide the order you study in and how long you spend on each chapter, not to cut chapters out.
Where can I practise these ETEA MDCAT Biology chapters?
Every chapter on this page links to its own free Biology MCQs on TestUstad, 19,844 questions across the 21 chapters ETEA MDCAT examines. Practice is free and unlimited with no account, and every question carries a written explanation of why the correct option is correct.
