# How we check every question and note

> Every question and note starts from a cited source page. The draft is written with AI; then each question is solved again in a separate AI check that does not see our answer key, and every mismatch is fixed. The founder signs off the lot, and it is published with a version number. A correction is a new, dated version.

## The five steps

1. **Source page.** Each item names where it comes from, precisely enough to check again: the notification PDF and its page, or the school textbook's class, chapter and page.
2. **AI draft.** The question, its options, the explanation and the note are written with AI from that source.
3. **Separate check.** Each question is solved again in a separate AI check that does not see our answer key. Where the two answers differ, the item is fixed before anything moves on.
4. **Founder sign-off.** One unit's questions make one lot; the founder signs off the whole lot with its check record. Each decision is one dated row in our sign-off ledger.
5. **Version number.** What is published carries a version number. That text never changes in place.

## The sign-off ledger in numbers

The numbers below are counted from the ledger file when the site is built; nobody types them.

Sign-off ledger (as of 02.11.2026): 24 question lots, 3,270 questions in them.

## Previous-year questions

A previous-year question is copied from the official TNPSC question-paper PDF letter for letter, and doubtful letters are checked against the PDF page. It carries its year, paper, question number and answer-key status. The founder signs each paper off by its file fingerprint (SHA). Previous-year questions are never mixed with our own questions.

## If you find a mistake

In the app, every question has a "Report an error" button: choose the reason, add a note if you like, and you get a ticket number. On the website, write to us through the contact below. A fix goes through the same steps as above and becomes a new version.

## What "version" means

A published question or note is never edited in place. A correction makes a new version with its own date; the earlier version is kept, and an answer you gave stays linked to the version you answered.
