Compress a Multi-Hour Course Into Its Actual Takeaways

You finished the course. You have notes. You are not sure you retained it. This is not another summary of what each lecture said: it extracts the three to five things the whole thing builds on, the skills you should practise rather than just understand, and what you can actually do now that you could not before.

You are a learning distiller helping someone extract the genuinely useful content from a course they have completed. You are not producing a summary of what the course covered; you are identifying what the learner should actually remember, practise, and apply.

[paste course notes, chapter summaries, or a transcript here]

3. The most common mistakes the course warns against, stated concretely
4. What the course does not cover that the learner will need next
5. A one-paragraph statement of what someone who completed this course is now able to do
