How this was worked out: We do not hold solved ETEA Engineering Admission Test papers yet. Chemistry on ETEA Engineering Admission Test examines the same chapters as ETEA MDCAT, NUMS, MDCAT, so the chapter shares measured across those 48 papers (2005 to 2025) are applied to the 30 Chemistry MCQs ETEA Engineering Admission Test actually carries. The ranking is measured; the totals are ETEA Engineering Admission Test's own. Once ETEA Engineering Admission Test papers are added here, this table is recomputed from them.

ETEA Engineering Admission Test Chemistry most important topics: frequently asked questions
What are the most important Chemistry topics for ETEA Engineering Admission Test 2026?
The highest-value ETEA Engineering Admission Test Chemistry chapters are s-Block and p-Block Elements (about 2.8 MCQs), Chemistry of Hydrocarbons (about 2.3 MCQs), Chemical Bonding (about 2.2 MCQs), Atomic Structure (about 1.9 MCQs) and Electrochemistry (about 1.5 MCQs). Together they account for 36 percent of the 30 Chemistry MCQs on the ETEA Engineering Admission Test paper. The ranking is derived rather than counted from ETEA Engineering Admission Test papers; the method is stated in full on this page.
How many Chemistry MCQs are on the ETEA Engineering Admission Test paper?
Chemistry is worth 30 MCQs on the ETEA Engineering Admission Test paper as set by Educational Testing and Evaluation Agency, spread across 25 chapters. This page ranks all 25 of them by how many of those MCQs each chapter is worth.
Are these ETEA Engineering Admission Test Chemistry numbers counted from past papers?
Not from ETEA Engineering Admission Test papers, and this page does not claim they are. TestUstad does not hold solved ETEA Engineering Admission Test papers yet. Chemistry on ETEA Engineering Admission Test examines the same chapters as ETEA MDCAT, NUMS and MDCAT, so the chapter distribution measured across those 48 papers is rescaled to the 30 Chemistry MCQs ETEA Engineering Admission Test carries. The order is measured, the totals are ETEA Engineering Admission Test's own.
Should I skip the low-priority Chemistry chapters for ETEA Engineering Admission Test?
No. Every chapter in this table appears on the ETEA Engineering Admission Test paper, and ETEA Engineering Admission Test 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 Engineering Admission Test Chemistry chapters?
Every chapter on this page links to its own free Chemistry MCQs on TestUstad, 13,720 questions across the 25 chapters ETEA Engineering Admission Test examines. Practice is free and unlimited with no account, and every question carries a written explanation of why the correct option is correct.
