How to use this workbook
1. Work through all 100 problems in order — topics are mixed on purpose so you build fluency, not memorization.
2. Each problem includes a short hint and the key concept it tests.
3. Circle your answer choice (A–D) for every problem.
4. Check your work against the Answer Key on the last page only after finishing.
5. Difficulty increases gradually (🥚 = 1 easiest, 🥚🥚🥚🥚🥚 = 5 hardest).
