Turn A Textbook Chapter Into A Revision Sheet

You have a chapter, a highlighter, and a nagging sense that none of it is going in. This takes the dense original and rebuilds it as a single page: the core ideas, how they link together, and the bits students usually muddle up. Good for the week before an exam when rereading everything is not an option.

<context>
You have a dense textbook chapter to revise before an exam. The subject is {SUBJECT} and the chapter covers [photosynthesis and cellular respiration].
</context>

<task>
**Condense the chapter into a one-page revision sheet:**
1. List the five to eight core concepts, each with a one-sentence definition
2. Show how the concepts connect (a short diagram in text form using arrows)
3. Flag two or three ideas that are commonly confused with each other and explain the difference
4. Write three practice questions with model answers
</task>

- Headed sections: Core Concepts, How They Connect, Common Confusions, Practice Questions
- Total length under 500 words so it fits on one page
