| Step | What to Do | Why It Works | |------|------------|--------------| | | Solve the question on your own (paper + Excel). | Struggles are learning moments. | | 2. Compare the Answer Key | Look at the final numeric answer only. Does yours match? | Quick sanity check; if not, you know something is off. | | 3. Study the Outline | Read the bullet‑point solution (no full derivations). Identify the key decision points —e.g., “use NPV, not IRR, because of multiple sign changes”. | You see the strategic path without being spoon‑fed every calculation. | | 4. Dive into the Full Walkthrough | Only after you’ve identified where you went wrong, read the detailed steps. Replicate each sub‑step in your notebook/Excel. | Reinforces each algebraic move; you learn the mechanics. | | 5. Re‑do the Problem Without Looking | Close the manual, redo the problem from scratch. | Tests whether you truly internalized the method. | | 6. Extend the Problem | Change an assumption (e.g., tax rate, project horizon) and redo the analysis. | Shows you can apply the framework flexibly. | | 7. Document Your Process | Write a brief “solution journal” entry: problem statement, your approach, where you deviated, what you learned. | Creates a personal knowledge base for future exams. |
