How Many Topics Deleted From JEE Main Physics Syllabus 2026
How Many Topics Deleted From the JEE Main Physics Syllabus 2026 explains the reduced syllabus, listing removed topics from Class 11 and 12 Physics. It outlines key deletions, reasons for NTA’s rationalisation, and how the syllabus reduction helps students focus on core, high-weightage concepts for effective exam preparation.
JEE Main Physics syllabus 2026 has undergone a significant reduction, with several topics removed from both Class 11 and Class 12 sections. While the core areas like Mechanics, Electrodynamics, and Modern Physics remain intact, less relevant or peripheral topics such as the Potentiometer, Transistor applications, Doppler Effect in sound, and parts of Thermodynamics and Oscillations have been deleted.
This change allows students to focus more on high-weightage chapters, strengthen conceptual understanding, and streamline their preparation for the exam.
JEE Main Physics Syllabus 2026 Deleted Topics
The syllabus reduction affects multiple units across both Class 11 and Class 12 Physics. The deleted topics were largely those considered redundant or less relevant to the fundamental engineering concepts tested in JEE Main.

Impact on Preparation of JEE Main 2026 Physics Deleted Syllabus
The removal of these topics, such as the Potentiometer and Transistor applications, means students no longer need to memorise complex circuit diagrams or specific characteristics associated with these devices. This allows for a deeper dive into core areas like Mechanics, Electrodynamics, and Modern Physics.
Deleted Chapters in JEE Main Physics 2026
While entire chapters are rarely removed, specific sections within units have been significantly pruned. For instance, the Communication Systems unit, which was once a staple of the JEE Main Physics syllabus, has been completely removed in recent years. This change simplifies the "Electronic Devices" and "Modern Physics" segments of the exam.
Why was JEE Main Physics Syllabus Reduction Done?
The NTA and the Ministry of Education initiated the JEE Main Physics syllabus reduction to match the rationalised NCERT textbooks. This ensures that students from various boards across India have a level playing field and are not burdened with topics that are no longer part of their school curriculum.
JEE Main Physics Syllabus Changes Preparation Strategy
With the JEE Main Physics syllabus 2026 being reduced, a smart preparation strategy is essential to focus on important topics. The following points highlight how students can adjust their study plan effectively to maximize scores.
-
Analyse the Weightage: With fewer topics, the importance of the remaining chapters, like Current Electricity (minus Potentiometer) and Magnetic Effects (minus Cyclotron) increases.
-
Focus on Concepts: Since the quantity of topics is reduced, the NTA may increase the conceptual depth of the questions.
-
Practice Updated Mock Tests: Use mock tests that reflect the reduced JEE Main Physics syllabus 2026 to get a real feel for the exam pattern.
