How to think it through

Type, method, check — “name the type, use its method, and check the answer against the question”

  1. Name the type of question.
  2. Use that lesson’s method — draw it if you can.
  3. Check the answer against every clue before you move on.

Use it for: Final revision before an Olympiad reasoning section, aptitude test or scholarship exam.

Worked example: Today is Monday. What day of the week will it be 45 days from today? Thursday

  1. 45 ÷ 7 = 6 remainder 3, so only 3 days matter.
  2. Monday + 3 days = Thursday.

Check: 42 days later is a Monday again; 3 more days is Thursday ✓
