Thinking tip

Question, check, reason, decide — “every critical thinking skill in one test”

  1. Find the topic of the question: questions (lessons 1–5), evidence (7–11), reasoning (13–17) or decisions (19–23).
  2. Use that lesson’s tip and read every option before you choose.
  3. If a fact is missing, say “not enough info”; if the rule does not decide it, say “can’t tell”; compare per day, not totals.

Use it for: Final revision, and every day afterwards.

Worked example: 🛠️ What is the first step in solving a problem? → know what is wrong

  1. Before trying anything, understand the problem.
  2. So the first step is to know what is wrong.
