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

ECAT Physics most important topics: frequently asked questions
What are the most important Physics topics for ECAT 2026?
The highest-value ECAT Physics chapters are Waves (about 3.3 MCQs), Force and Motion (about 2.9 MCQs), Nuclear Physics (about 2.6 MCQs), Current Electricity (about 2.2 MCQs) and Electromagnetism (about 2.1 MCQs). Together they account for 44 percent of the 30 Physics MCQs on the ECAT paper. The ranking is derived rather than counted from ECAT papers; the method is stated in full on this page.
How many Physics MCQs are on the ECAT paper?
Physics is worth 30 MCQs on the ECAT paper as set by University of Engineering and Technology, Lahore, spread across 20 chapters. This page ranks all 20 of them by how many of those MCQs each chapter is worth.
Are these ECAT Physics numbers counted from past papers?
Not from ECAT papers, and this page does not claim they are. TestUstad does not hold solved ECAT papers yet. Physics on ECAT examines the same chapters as MDCAT, ETEA MDCAT and NUMS, so the chapter distribution measured across those 48 papers is rescaled to the 30 Physics MCQs ECAT carries. The order is measured, the totals are ECAT's own.
Should I skip the low-priority Physics chapters for ECAT?
No. Every chapter in this table appears on the ECAT paper, and ECAT 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 ECAT Physics chapters?
Every chapter on this page links to its own free Physics MCQs on TestUstad, 13,934 questions across the 20 chapters ECAT examines. Practice is free and unlimited with no account, and every question carries a written explanation of why the correct option is correct.
