Error Book

Overview

Each entry stores the question text, your answer, the correct answer, and metadata (subject, topic, chapter) so you can filter later. Entries also remember their source — which test, DPP, mock series, or manual add put them there.

How entries get added

Entries appear automatically when:

• You submit a wrong MCQ on a DPP.
• You submit a wrong answer in a test or mock test.
• An AI-graded question is marked partial / wrong.

You can also add a question yourself — see "Adding a question manually" below.

Browsing your error book

Open Dashboard → Error book. The list is paginated 20 entries at a time, newest first. Each card shows:

• The question (LaTeX renders correctly).
• Your answer and the correct answer side by side.
• Subject / topic / chapter chips for filtering.
• Source — e.g. "DPP", "Test #123", "Mock series JEE Main 2025", "Manual".
• Revision status — Unrevised / Revised.

Filters

Use the filter bar to narrow by:

• subject — e.g. Physics
• topic — e.g. Rotational Motion
• isRevised — show only unrevised, or only revised

Combine filters: e.g. "Physics + Rotational Motion + Unrevised" gives you exactly the open work for tonight's revision session.

Marking as revised

On any entry, click Mark as revised after you've re-attempted and understood the question. Revised entries stay in the book for reference but drop out of the default "Unrevised" view.

Adding your own note

The errorNote field is yours — write the misconception that caused the mistake (e.g. "I forgot to convert grams to kilograms"). When you next revise, scanning notes is faster than re-reading the explanation.

Adding a question manually
