What changed since 2020–22

Most chapters held steady. Among chapters marked rising, the biggest changes were in Aldehydes & Ketones, from about 0.3 to about 0.8 questions per shift, and Relations & Functions (Basic), from about 0.6 to about 1.1. Among those marked falling, the biggest change was in Applications of Derivatives, from about 1.4 to about 0.8; it lost some topics in the 2024 syllabus cut.

Trend compares with 2020–22: rising when the 2024–26 rate is about 1.5 times the 2020–22 rate or more, falling when it is about two-thirds of it or less. The 2024–26 average must also differ by about 0.3 questions per shift or more, and the change must show in at least two of the three years 2024–26. Otherwise steady.

How to read the tables

Frequently asked

Which chapters have the highest weightage in JEE Main?

In the 2024–26 papers, these chapters had about 1.3 or more questions per shift in our question bank, the ones marked high in the tables above.

  • Physics: Ray Optics; Current Electricity; Moving Charges & Magnetism; Units, Dimensions & Errors; and Rotational Motion (about 1.3–1.6 questions per shift each).
  • Chemistry: General Organic Chemistry (GOC), Coordination Compounds, Chemical Bonding & Molecular Structure, d & f Block Elements, Amines & Diazonium Salts, Electrochemistry, Mole Concept & Stoichiometry, Atomic Structure and Chemical Thermodynamics (about 1.3–2.2 questions per shift each).
  • Mathematics: Three Dimensional Geometry, Sequences & Series, Definite Integration, Vectors and Differential Equations (about 1.4–1.8 questions per shift each).

Is the weightage the same every year?

No. The count moves from shift to shift and year to year. In our bank, General Organic Chemistry (GOC) had about 3.4 questions per shift in 2024 and about 1.3 in 2026, while Aldehydes & Ketones went from about 0.4 to about 1.5. The tables call a chapter rising or falling only when the change since 2020–22 is large and shows in at least two of the three years 2024–26; most chapters were steady. For 2026 on its own, see the JEE Main 2026 most asked chapters.

How were these numbers counted?

We counted every question from the 2020–2026 JEE Main papers in PrepWiser's question bank, chapter by chapter, and divided by the number of shifts in each period. The bank holds about 86–87 questions per shift for 2021–24 and about 74–75 for 2025–26. The papers themselves had 90 questions in 2021–24, when each subject offered 10 numerical questions and students answered 5, and 75 in 2020 and 2025–26. A chapter's share is its part of the subject's questions in the 2024–26 papers. PrepWiser splits the syllabus into about 100 chapters, so a large NTA unit such as Calculus appears as several. A few questions may be missing or tagged to a different chapter, so treat the figures as approximate.

Does weightage tell me what will come in 2027?

No. These are counts from past papers, and NTA can set questions from any chapter on the syllabus in any shift. NTA has not published the JEE Main 2027 syllabus yet (as of October 2026). The 2025 and 2026 syllabi were the same as 2024's, apart from Physics no longer listing vector topics under kinematics (vectors are still in Maths). NTA's tentative calendar puts the first session in late January 2027, with details to come in the information bulletin. This page will be updated when the 2027 syllabus is out.

Counted from PrepWiser's JEE Main question bank (2020–2026 papers).
