How this was worked out: We do not hold solved NED papers yet. Chemistry on NED 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 30 Chemistry MCQs NED actually carries. The ranking is measured; the totals are NED's own. Once NED papers are added here, this table is recomputed from them.

NED Chemistry most important topics: frequently asked questions
What are the most important Chemistry topics for NED 2026?
The highest-value NED Chemistry chapters are s-Block and p-Block Elements (about 2.8 MCQs), Chemical Bonding (about 2.1 MCQs), Chemistry of Hydrocarbons (about 2.1 MCQs), Atomic Structure (about 1.9 MCQs) and Fundamental Concepts of Chemistry (about 1.6 MCQs). Together they account for 35 percent of the 30 Chemistry MCQs on the NED paper. The ranking is derived rather than counted from NED papers; the method is stated in full on this page.
How many Chemistry MCQs are on the NED paper?
Chemistry is worth 30 MCQs on the NED paper as set by NED University of Engineering and Technology, spread across 25 chapters. This page ranks all 25 of them by how many of those MCQs each chapter is worth.
Are these NED Chemistry numbers counted from past papers?
Not from NED papers, and this page does not claim they are. TestUstad does not hold solved NED papers yet. Chemistry on NED examines the same chapters as MDCAT, NUMS and ETEA MDCAT, so the chapter distribution measured across those 37 papers is rescaled to the 30 Chemistry MCQs NED carries. The order is measured, the totals are NED's own.
Should I skip the low-priority Chemistry chapters for NED?
No. Every chapter in this table appears on the NED paper, and NED 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 NED Chemistry chapters?
Every chapter on this page links to its own free Chemistry MCQs on TestUstad, 13,720 questions across the 25 chapters NED examines. Practice is free and unlimited with no account, and every question carries a written explanation of why the correct option is correct.
