JEE Main & Advanced 2026: NCERT Deleted Topics That Still Matter
On this page
TL;DR for JEE 2026 aspirants: NCERT removed roughly 30 percent of Class 11-12 PCM content in 2022, but the NTA JEE Main + Advanced syllabus is a separate document — and several deleted NCERT topics remain testable. Below is a chapter-wise reconciliation. Always cross-check with the official NTA JEE 2026 information bulletin before exam day.
Every year, JEE aspirants ask: if a topic was removed from my NCERT textbook, can I skip it for JEE? The answer is only sometimes. NTA maintains the JEE Main and JEE Advanced syllabi independently of NCERT's textbook revisions. The current JEE 2026 syllabus is closer to the pre-2022 NCERT than to your current Class 11-12 books.
This page reconciles three sources for JEE 2026 PCM:
- Topics deleted from NCERT 2022-26 — straight from the official NCERT rationalisation booklets.
- The NTA JEE 2026 syllabus — published in the latest information bulletin.
- The intersection — i.e. what's gone from your textbook but still in the JEE syllabus you're being tested on.
JEE 2026 — deletion-vs-syllabus reconciliation
| Subject | NCERT 2022 deletions | Still in JEE 2026 syllabus? | Where to read it |
|---|---|---|---|
| Mathematics — Class 11 | Mathematical Induction (full chapter), Mathematical Reasoning (full chapter) | Yes — both still in JEE Main + Advanced | Pre-2022 NCERT Class 11 Maths; coaching modules |
| Mathematics — Class 12 | Selected Statistics derivations | Mostly retained — proofs may be skipped, results tested | Old NCERT + JEE problem banks (Cengage, Arihant) |
| Physics — Class 11 | Heat Engines and Carnot Cycle derivations, specific oscillation proofs | Mostly retained — derivations may be skipped, applications tested | HC Verma + old NCERT |
| Physics — Class 12 | Communication Systems (entire chapter dropped), some Logic Gates derivations | Communication Systems removed from JEE 2024 onwards. Logic Gates partially retained — review from old NCERT | Skip Communication Systems for JEE; revise Logic Gates from old NCERT |
| Chemistry — Class 11 | Hydrogen subtopics, States of Matter equations, s-Block details, environmental chemistry partial | Mostly retained — Hydrogen, States of Matter equations, s-Block periodic chemistry are all in JEE | Old NCERT Class 11 Chemistry |
| Chemistry — Class 12 | The Solid State, Surface Chemistry, General Principles of Isolation, p-Block partial, Polymers, Chemistry in Everyday Life | Partially — Polymers and Solid State retained. Surface Chemistry, Isolation Principles dropped from JEE 2024+ | Old NCERT Class 12 Chemistry + NTA bulletin |
Verification for JEE 2026: the NTA JEE 2026 syllabus document at jeemain.nta.ac.in is the single source of truth. If a topic appears in our table as 'still in JEE' but was removed from the NTA syllabus, the NTA document wins.
Strategy: studying deleted-but-tested topics for JEE 2026
- Don't trust your school textbook alone. Class 11-12 books in 2025-26 are post-rationalisation; they don't cover every JEE-tested subtopic.
- Get a copy of the pre-2022 NCERT for PCM. Old editions are widely archived; coaching institutes redistribute the deleted chapters as free PDFs.
- Solve last 5 years of JEE Main + Advanced papers before deciding what to skip. If a deleted topic appears in 2+ recent papers, it's still high-priority despite the textbook removal.
- Track changes once during prep — once at start, once mid-year (after NTA's bulletin in February), once one month before exam. Don't churn on this monthly.
