How to Use This Well
Use the released exam as a self-check, not just an answer hunt.
- Try the exam first under realistic conditions.
- Use the equation sheet, but not your notes.
- Check your reasoning with the solutions page.
- Revisit the Module 1 readings for any concept that still feels shaky.
