Top 15 most important AKU topics, all subjects
Every chapter on the AKU paper on one scale, heaviest first. Covers 171 of the 180 MCQs on the paper. Analytical and Logical Reasoning is left off this combined list because no solved paper TestUstad holds measures it, and an estimate does not belong in a column of counted numbers. It has a ranked table further down.

AKU most important topics: frequently asked questions
What are the most important topics for AKU 2026?
The highest-value AKU chapters are Biodiversity and Variety of Life (Biology, about 12.1 MCQs), Cell Structure and Function (Biology, about 9.8 MCQs), Coordination and Control (Biology, about 7.7 MCQs), Biological Molecules (Biology, about 6.5 MCQs) and Waves (Physics, about 4.6 MCQs). That ranking comes from the Aga Khan University subject weightage for AKU combined with the chapter distribution measured across the 37 solved papers TestUstad holds for the same chapters. Every one of these chapters has free MCQs on TestUstad.
Is it enough to study only the most important AKU topics?
No, and no honest ranking says otherwise. The top chapters on this page are where your first hours should go because they carry the most marks per hour, but AKU is a competitive exam decided by a few marks, and the chapters at the bottom of this table still appear on the paper every year. Use this order to decide what to do first and what to revise last, not what to skip.
Where do these AKU topic rankings come from?
TestUstad does not hold solved AKU past papers yet, and this page does not pretend otherwise. The ranking is built from the Aga Khan University subject weightage for Aga Khan University Admission Test, combined, for subjects whose chapters are also examined by papers TestUstad has counted, with the chapter distribution measured across those papers. Each subject page states exactly which of the two applies to it.
How many MCQs is each AKU chapter worth?
Chapter by chapter, that is exactly what the tables on this page show. The single heaviest chapter on the AKU paper is Biodiversity and Variety of Life at about 12.1 MCQs, and the subject pages break down every remaining chapter the same way.
Can I practise the most important AKU topics free?
Yes. Every chapter listed on this page links to free MCQs on TestUstad, with unlimited attempts, no daily limit, no card and no account needed to start. Each question carries a written explanation of why the correct option is correct, so a chapter you are weak in teaches you as you work through it.
