Quick Summary: JEE Main 2026 may follow the reduced syllabus used earlier. Physics had topics removed like vectors, communication devices, capacitors, and radioactivity. Chemistry saw chapters like States of Matter, Surface Chemistry, Polymers, and Environmental Chemistry removed. Maths dropped Mathematical Induction, Reasoning, and some 3D Geometry. The blog also lists added topics, previous year deletions, and subject-wise comparison.
The National Testing Agency (NTA) released the syllabus of JEE Main 2026 in October 2025 on its official website, jeemain.nta.nic.in. If there is any information on JEE Main Deleted Syllabus 2026, seeing which the syllabus is reduced or updated then candidates can check the same from its official website (idioms website) directly. Last year, there were no big changes in the NTA JEE Main syllabus 2026, but a few topics were removed from Physics. Some of these include Scalars and Vectors, Addition and Subtraction of Vectors, Scalar and Vector Products, Unit Vectors, and Resolution of Vectors.
Students who are preparing for the exam must go through the JEE Main reduced syllabus 2026 to know which chapters have been removed. JEE Main entrance exam 2026 will be conducted in January and April 2026 by NTA, and the actual JEE Main 2026 Question Papers will be developed on the basis of this newly updated JEE Main 2026 Deleted Syllabus.
