NUMS most important topics: frequently asked questions
What are the most important topics for NUMS 2026?
The highest-value NUMS chapters are Cell Structure and Function (Biology, about 9.0 MCQs), Biodiversity and Variety of Life (Biology, about 7.0 MCQs), Force and Motion (Physics, about 6.5 MCQs), Grammar (English, about 5.6 MCQs) and Comprehension (English, about 5.2 MCQs). That ranking comes from counting every MCQ in the 7 solved NUMS past papers on TestUstad and matching each one to its chapter. Every one of these chapters has free MCQs on TestUstad.
Is it enough to study only the most important NUMS 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 NUMS 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.
How does TestUstad decide which NUMS topics are most important?
By counting. Every MCQ in the 7 solved NUMS past papers on TestUstad is tagged to the chapter it tests, which gives each chapter's measured share of its subject. That share is then applied to the MCQs the current NUMS pattern gives the subject, so the figures describe the paper being sat now rather than the older papers they were measured on. Nothing here is an opinion about which chapters feel important, and where TestUstad has not counted real papers for a subject the page says so on that subject's own page instead of implying it did.
How many MCQs is each NUMS chapter worth?
Chapter by chapter, that is exactly what the tables on this page show. The single heaviest chapter on the NUMS paper is Cell Structure and Function at about 9.0 MCQs, and the subject pages break down every remaining chapter the same way.
Can I practise the most important NUMS 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.
