If you are preparing for JEE Main 2026, one of the smartest preparation strategies is to understand the JEE Mains 2026 Deleted Syllabus before you start studying seriously.
Many aspirants waste months preparing chapters that are no longer part of the exam — and this directly impacts revision time, mock test practice, and score improvement.
In this blog, you will get:
Latest subject-wise deleted topics
Chapters removed from Physics, Chemistry & Mathematics
Important updates based on NCERT rationalisation
Smart preparation strategy after syllabus reduction
JEE Main 2026 Latest Syllabus Update
According to the official syllabus released by the National Testing Agency, the JEE Main 2026 syllabus remains the same as the revised syllabus introduced earlier, which means previously removed topics are still excluded from the exam this year.
This syllabus revision was done to align the entrance exam with the updated NCERT curriculum and reduce academic burden.
Reports suggest that approximately 15% of the total syllabus has been reduced, while nearly 85% remains unchanged across Physics, Chemistry, and Mathematics.
That means if you are still studying deleted topics, you are preparing beyond the required syllabus.
JEE Mains 2026 Deleted Topics – Physics
Understanding the JEE Mains 2026 Deleted Syllabus in Physics will help you avoid low-return chapters.
Completely Removed Chapters
Communication Systems (Entire Chapter)
Partially Deleted Topics
From different chapters, the following topics are no longer included:

These deletions indicate that Physics in 2026 will be more focused on core numericals and conceptual mechanics instead of experimental theory portions.
JEE Mains 2026 Deleted Syllabus – Chemistry
Chemistry has seen the maximum number of deleted chapters in recent syllabus rationalisation.
Entire Chapters Removed
States of Matter (Gaseous & Liquid)
Surface Chemistry
Hydrogen
s-Block Elements
Metallurgy (Isolation of Metals)
Environmental Chemistry
Polymers

Additionally, certain theoretical portions were removed from:
Atomic Structure
Thomson Model
Rutherford Model & Limitations
Some Basic Concepts of Chemistry
Physical Quantities
Precision
Accuracy
Significant Figures
p-Block Elements
Detailed Group-wise Preparation & Properties (Reduced)
This clearly shows that memory-based inorganic content has been reduced significantly for JEE Main 2026.
JEE Mains 2026 Deleted Syllabus – Mathematics
Mathematics syllabus has undergone selective but important topic deletion.
Entire Chapters Removed

Coplanar Lines
Vector Algebra
Scalar Triple Product
Vector Triple Product
Statistics
Bernoulli Trials
Binomial Distribution
These changes mean Mathematics preparation should now be more focused on Calculus, Coordinate Geometry, and Algebra fundamentals.
Why Were These Topics Removed?
The removal of these topics is mainly due to:
NCERT rationalisation policy
Reduced theoretical overload
Concept-based evaluation approach
NEP-aligned curriculum structure
The objective is to test application and understanding, rather than memorisation of outdated or overly descriptive content.
