Frequently Asked Questions

Is the JEE Advanced 2027 syllabus the same as 2026?

The JEE Advanced 2026 syllabus is identical to 2025. The organising IIT typically retains the syllabus year-on-year unless a formal revision is announced. The 2027 syllabus is expected to remain the same, and this page will update if there are changes.

Is JEE Advanced syllabus larger than JEE Main?

JEE Advanced covers roughly the same NCERT topics as JEE Main but goes deeper. Some Advanced-only topics include Solid State, Surface Chemistry, and Polymers in Chemistry, plus more advanced problems in Physics and Maths overall.

Who conducts JEE Advanced?

JEE Advanced is conducted by one of the seven zonal IITs on a rotating basis under the guidance of the Joint Admission Board. IIT Bombay, IIT Delhi, IIT Kanpur, IIT Kharagpur, IIT Madras, IIT Roorkee, and IIT Guwahati take turns.
