Turn Scattered Notes Into A Structured Study Guide

Notes taken in the moment rarely make sense a week later: half-finished sentences, points repeated twice, and gaps where you were distracted. This organises them under clear headings, flags what seems to be missing, and adds a quick self-test at the end. Suits students turning raw notes into something usable before an exam.

<context>
You have messy, unstructured notes from lectures or reading on {SUBJECT}. They are out of order and repeat some points while missing others entirely. Notes: {NOTES_TEXT}

<task>
**Turn the notes into a structured study guide:**
1. Group related points under clear headings, removing duplication
2. Flag anywhere the notes seem incomplete or contradictory, and note what is missing
3. Add a short summary paragraph at the top giving the big picture
4. End with a five-question self-test based only on what is in the notes

- Summary paragraph, then headed sections, then a self-test section
- Flag list of gaps, if any, at the end
