CBSE 2026-27 me kya hata — aur NEET/JEE me usme se kya wapas aata hai
Board se hata hua topic hamesha safe-to-skip nahi hota. Neeche apna mode chuno — poori list turant filter ho jayegi.

Chapter pe click karo, poori deleted-topics list khul jayegi. 2025-26 ki rationalisation 2026-27 me carry forward hui hai (cbseacademic.nic.in par verify kar sakte ho).
- Paper-strip electroscope activity
- Earthing ka concept
- Charging by Induction
- Capacitor me stored energy ki derivation
- Correction (verified against official CBSE PDF): Meter Bridge hata nahi hai — ye abhi bhi CBSE ka listed Practical #3 hai ("meter bridge se resistance nikalna"). Pehle isko galti se deleted bata diya tha.
- Sirf Potentiometer wala experiment (EMF comparison / internal resistance) CBSE ki official "List of Practicals" se hata hai — apparatus abhi bhi identification-list me hai, par koi numbered experiment nahi bacha.
- Velocity Selector, Cyclotron, Toroid
- Magnetic dipole moment of revolving electron
- Bar magnet ka solenoid-jaisa mathematical treatment
- Earth's Magnetism, Declination/Dip
- Curie's Law aur temperature, Hysteresis
- Energy Consideration (quantitative), Eddy Currents
- Series LCR ka analytical solution
- Sharpness of Resonance, LC Oscillations
- Mirage, Diamond refraction, Rainbow, Scattering of Light
- Doppler Effect
- YDSE ki full derivation (official syllabus: "fringe width — no derivation, final expression only" — formula abhi bhi hai)
- Resolving Power
- Polarisation by Scattering/Reflection
- De Broglie wavelength ki derivation
- Heisenberg Uncertainty
- Davisson-Germer Experiment
- Spectral Series
- Bohr Model ki full derivation
- Line Spectra
- Radioactive Decay Law
- Alpha/Beta/Gamma Decay
- Nuclear Reactor
Chemistry
Official CBSE 2026-27 syllabus PDF se verify kiya — 10 numbered theory units (Solutions se Biomolecules tak) hi ab board-exam ke liye "summative" (marks wale) hain. Solid State poori tarah syllabus se bahar hai — kahin mention nahi. Baaki 4 topics niche table me hain, par inki asli status "poora hata" nahi hai — official document ki apni language yahi hai:
| Topic | Board written exam (summative) | Practical exam |
|---|---|---|
| Solid State | Poori tarah syllabus se bahar (unit list me hai hi nahi) | — |
| Surface Chemistry | Formative only — theory exam me nahi poochha jayega | ✅ Practical me abhi bhi hai (sol preparation experiment) |
| General Principles of Isolation of Elements | Formative only | — |
| Polymers | Formative only | — |
| Chemistry in Everyday Life | Formative only | — |
Matlab: board ke written paper me sirf Solid State poori tarah safe-to-skip hai. Baaki 4 topics class me padhaye jaate hain, kabhi-kabhi practical me bhi aate hain — sirf theory board exam ke marks me nahi jodte. NEET/JEE comparison abhi is page me sirf secondary sources se hai (official NTA/NMC PDF access nahi ho paya, neeche footer me detail hai) — usi wajah se "✅ NEET se bhi hata" wala pehla claim hata diya, kyunki wo bhi primary-source-verified nahi tha.
Mathematics
- Composition of functions, invertible functions ka formal treatment
- Rolle's aur Lagrange's Mean Value Theorems (official 2026-27 syllabus me kahin mention nahi)
Biology
Asli, verified deletion sirf ek hai:
| Topic | Status (official PDF se verbatim) |
|---|---|
|
Environmental Issues (air/water pollution, solid waste, greenhouse effect, ozone depletion, deforestation) |
"Available as a part of CBSE Reading Material" — formative only, summative (marks wale) board exam me nahi poochha jayega. Chemistry jaisi hi category. |
13 official chapters me se sirf yahi ek topic "formative-only" list me hai — baaki poora Biology syllabus (Reproduction, Genetics, Evolution, Human Health, Biotechnology, Ecosystem, Biodiversity) fully board-exam-tested hai.
