According to reports available, several topics from the traditional Class 11 and 12 Physics syllabus have been officially removed from the JEE Main 2026 syllabus. These deletions align with efforts to rationalize the syllabus and concentrate on core concepts while reducing the study load for aspirants.
Why the Syllabus Was Reduced
Students preparing for JEE Main often juggle extensive CBSE Class 11–12 boards plus engineering exam preparation. The NTA’s rationalization aims to:
- Simplify preparation focus
- Help students dedicate more time to high-weightage concepts
- Align the JEE syllabus more closely with core NCERT fundamentals
(Though some sources note that the official NTA syllabus for 2026 hasn’t formally listed deletions yet, many coaching platforms and prep resources are operating based on the tentative deleted list carried forward from recent years.)
Physics — Deleted Topics (Class 11 & 12)
The table below lists the major topics reportedly removed from the JEE Main 2026 Physics syllabus:
| Unit / Chapter | Deleted Topics |
|---|---|
| Physics & Measurement | Physics, technology & society; Accuracy & precision of instruments |
| Kinematics | Zero Vector |
| Properties of Solids & Liquids | Reynolds number; Newton’s law of cooling |
| Thermodynamics | Carnot engine & its efficiency |
| Oscillations & Waves | Free, forced, damped oscillations; Resonance; Doppler Effect in sound |
| Current & Electricity | Resistance of different materials; Colour code for resistors; Potentiometer (principle & applications) |
| Magnetic Effects of Current | Cyclotron; Magnetic susceptibility & permeability; Hysteresis; Electromagnets/permanent magnets |
| Electromagnetic Induction | Quality factor |
| Optics | Resolving power of microscopes & astronomical telescopes |
| Atoms & Nuclei | Isotopes, isobars, isotones; Radioactivity laws & particle properties |
| Electronic Devices | Junction transistor theory; Transistor as amplifier, oscillator, switch; Characteristics of transistor |
| Chemistry & Mathematics | As of now:
|
What This Means for Aspirants
Do These Deleted Topics Never Appear in JEE Main?
Not necessarily. Some aspirants and coaching discussions point out that deleted topics may still be referenced in questions or underlying concepts — even if officially removed — especially if they are part of Class 11–12 fundamentals.
Preparation Strategy Recommendations
Prioritize core
high-weightage topics in Physics, Chemistry, and Mathematics.
Use the official syllabus PDF released by NTA as the primary reference.
Review older deleted topics if time permits — especially those that link to
core concepts.
