How this was worked out: We do not hold solved DUHS papers yet. Chemistry on DUHS examines the same chapters as MDCAT, NUMS, ETEA MDCAT, so the chapter shares measured across those 37 papers (2005 to 2025) are applied to the 45 Chemistry MCQs DUHS actually carries. The ranking is measured; the totals are DUHS's own. Once DUHS papers are added here, this table is recomputed from them.

DUHS Chemistry most important topics: frequently asked questions
What are the most important Chemistry topics for DUHS 2026?
The highest-value DUHS Chemistry chapters are s-Block and p-Block Elements (about 4.2 MCQs), Chemical Bonding (about 3.2 MCQs), Chemistry of Hydrocarbons (about 3.2 MCQs), Atomic Structure (about 2.9 MCQs) and Fundamental Concepts of Chemistry (about 2.4 MCQs). Together they account for 35 percent of the 45 Chemistry MCQs on the DUHS paper. The ranking is derived rather than counted from DUHS papers; the method is stated in full on this page.
How many Chemistry MCQs are on the DUHS paper?
Chemistry is worth 45 MCQs on the DUHS paper as set by Dow University of Health Sciences, spread across 25 chapters. This page ranks all 25 of them by how many of those MCQs each chapter is worth.
Are these DUHS Chemistry numbers counted from past papers?
Not from DUHS papers, and this page does not claim they are. TestUstad does not hold solved DUHS papers yet. Chemistry on DUHS examines the same chapters as MDCAT, NUMS and ETEA MDCAT, so the chapter distribution measured across those 37 papers is rescaled to the 45 Chemistry MCQs DUHS carries. The order is measured, the totals are DUHS's own.
Should I skip the low-priority Chemistry chapters for DUHS?
No. Every chapter in this table appears on the DUHS paper, and DUHS 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 DUHS Chemistry chapters?
Every chapter on this page links to its own free Chemistry MCQs on TestUstad, 13,720 questions across the 25 chapters DUHS examines. Practice is free and unlimited with no account, and every question carries a written explanation of why the correct option is correct.
