Understand a little. Practice once. Write your own plan. Each lesson explains an idea with an example, then asks you to answer a question and write a short reason before reading the explanation. Gather your thoughts as you learn, then follow the prompts to write your own learning or investment plan.

08 · Review reasoning, not just outcomes
What you’ll learn
Learn to revisit your earlier thinking and identify what to improve.
A review looks back at what you knew, why you formed a view, and what happened later. Record four things: observed facts, information sources, uncertainties, and your next check. This gives you more to learn from than simply noting that a price rose or fell.
Many factors affect an outcome. One rise does not prove your method is reliable, and one decline does not automatically mean your judgment was wrong. Review the information and plan you had at the time, recording later discoveries separately as new information.
See it in an example
Suppose you saw revenue growth and wrote that the company’s share price might rise. It later did. Your review should still ask whether you checked profits and valuation and recorded supporting evidence. If not, add those checks to your next plan rather than skipping research because the outcome was favorable.
Use what you just learned to answer a question
Choose the answer you think fits and write a short reason in your own words. Then submit to see the answer and explanation and check your understanding.
Try this for yourself
Revisit one observation and add the facts, sources, uncertainties, and next step. Ask what new information would change your mind. If records are missing, it is fine to leave the assessment open.
