Copyright, sources & corrections

Original content

The notes, diagrams (SVG), practice questions and videos are original to Simple Learning Hub.

NCERT textbooks

NCERT textbooks are copyrighted. We do not host or re-upload their PDFs — the "Open on NCERT official website" button opens ncert.nic.in directly.

Previous year papers

Every paper lists its board, year, set code and source. We never call a copy taken from a third-party archive an official upload. We never call a model/sample paper a board paper.

JEE / NEET papers and answer keys

Papers and answer keys of JEE Main, JEE Advanced and NEET UG are owned by NTA / the IITs. A public PDF is not automatically free to re-publish, so SLH links to the official file and does not host a copy until permission or a lawful basis has been confirmed. For every linked file we keep a source record: owner, official URL, date checked, and whether it is hosted (data/pyq/entrance-official-links.csv). Provisional and final answer keys are labelled as the official site labels them.

What SLH makes vs what is official

Pages show labels: Official source (linked from NTA / IIT / NMC / CBSE / UPMSP / NCERT), NCERT foundation, SLH original (our notes, diagrams, simulators, questions) and SLH practice test — not official (our mock tests). We do not scrape protected content, remove watermarks or copy paid coaching material. Rights holders can ask for removal through the contact page.

Corrections

Report any mistake through the contact page or the "Report a mistake" button (it copies the page and question reference for an Instagram DM). Content is updated when a report is confirmed correct.
