Let us start with the thing nobody tells you straight.
There is no NEET(UG) 2027 syllabus yet. NMC has not released one. The latest official document is Syllabus for NEET (UG) – 2026, and that is what you study from today. If a website is showing you a “2027 deleted list”, it is showing you the 2026 document with a new year typed on top.
And here is the second thing. NMC never publishes a deleted-topics list. It publishes the syllabus, and that is all. Every deleted-syllabus list you have seen is somebody sitting down with the old document and the new one and writing out the difference by hand. That is why no two lists agree, and why some of them are simply wrong.
So below is that comparison, done carefully, against the official document itself.
What is out of NEET(UG) Physics
Gone completely
- Communication Systems — the entire chapter.
Semiconductors
- Junction transistor, transistor action and characteristics
- Transistor as an amplifier (common emitter), as an oscillator, as a switch
Waves and Oscillations
- Doppler effect in sound
- Free, forced and damped oscillations, and resonance
Current Electricity
- Potentiometer and its applications
- Carbon resistor colour code
- Resistances of different materials
Alternating Current
- Quality factor
Magnetism
- Cyclotron
- Earth’s magnetic field and magnetic elements
- Permanent magnets and electromagnets
- Hysteresis
- Magnetic susceptibility and permeability
- Magnetic dipole moment of a revolving electron
Mechanics, Fluids and Thermal
- Geostationary satellites
- Reynolds number
- Newton’s law of cooling
- Carnot engine and its efficiency
- Poisson’s ratio and elastic energy
- Stefan’s law, Wien’s displacement law, black-body radiation, greenhouse effect
Modern Physics
- Davisson–Germer experiment
- Isotopes, isobars and isotones
- The whole of radioactivity — alpha, beta and gamma rays, the radioactive decay law, half life, mean life and activity
Optics
- Resolving power of the microscope and the telescope
- Deviation and dispersion of light by a prism, which takes dispersive power and angular dispersion with it
- Human eye and its defects
- Scattering of light and the blue sky
Electrostatics and EMI
- Van de Graaff generator
- LC oscillations
What is still IN, even though lists call it deleted
This is the half that costs students marks, because they skip a topic that is very much in the paper.
- Logic gates — OR, AND, NOT, NAND, NOR. Transistors are out. Logic gates are not.
- Microscope and astronomical telescope, and their magnifying powers. Several big coaching sites list this as deleted. The official document keeps it, word for word. Only the resolving power went.
- Zener diode and Zener as a voltage regulator, LED, photodiode, solar cell, diode as a rectifier.
- Second law of thermodynamics, reversible and irreversible processes. The Carnot engine that illustrates it is gone. The law itself is not.
- Metre bridge, Wheatstone bridge, Kirchhoff’s laws, temperature dependence of resistance. Only the potentiometer left Current Electricity.
- Modulus of rigidity. LCR series resonance. Standing waves in organ pipes, and the resonance tube in Experimental Skills.
- Para-, dia- and ferromagnetic substances with examples, and the effect of temperature on magnetic properties.
- Scalars and vectors — addition and subtraction, scalar and vector products, unit vector, resolution of a vector. All of it stays in Kinematics.
How to use this list
Do not treat a deleted list as free marks. Treat it as permission to stop worrying about a few things, so the time goes where the paper actually is.
Two honest cautions.
One. If a topic is out of the syllabus but a question in your module is built on it, you can skip that question. You cannot skip the idea underneath it. Resonance is out of Oscillations as a listed topic, but LCR series resonance is in, and it is the same physics wearing different clothes.
Two. Reading a syllabus does not tell you where you stand. Only a clock does. You can know every line of what is in and what is out and still lose twenty marks because the questions you could solve took too long.

A syllabus list cannot tell you what you would score today.
Only a timed paper can.
