Turn Lecture Notes Into a Study Guide

    Turn my notes into an organized study guide.

The notes / transcript (paste them):
{{notes}}

Subject / focus (optional): {{focus}}

Produce a study guide with:
- **Overview** — a short summary of what this material covers.
- **Key terms & definitions** — the important vocabulary, each defined simply.
- **Main points** — the core ideas, organized by theme or topic, as clear bullets.
- **Worth memorizing** — any formulas, dates, or facts to know cold.
- **Test yourself** — a handful of questions covering the material (with brief answers at the end).

Base it ONLY on my notes — organize and clarify what's there; don't add outside facts or fill gaps with invented content. If my notes are unclear or seem to have a gap on an important point, flag it as "unclear in notes — check this" rather than guessing.
