Level 1 · Warm-up
1 How many people should a study group have?
Show worked solution
Two to four. Larger and it becomes an audience rather than a set of teachers.
2 What are the four pillars of the framework, in order?
Show worked solution
FIT · ASK · TEST · TEACH. Body ready, questions driving, retrieval proving, teaching finishing.
Level 2 · Core
3 You tell yourself "I'll teach this to someone sometime" but never arrange it. Why does the protégé effect fade?
Show worked solution
The effect comes from a genuine expectation. No person and no date means no expectation, so your studying does not change.
4 A group member arrives having read nothing and asks the others to explain the whole chapter. What rule has been broken?
Show worked solution
Prepare beforehand. A group is not first contact with the material — unprepared members turn it into a group read-through.
Level 3 · Challenge
5 Why is bluffing an answer worse than admitting you do not know?
Show worked solution
Two harms: your listener learns something false, and you lose the diagnostic information the question just gave you.
6 A student always teaches classmates who already understand the topic well. Why is this comfortable but weak?
Show worked solution
An expert listener silently patches your gaps from their own knowledge, so nothing gets exposed. A non-expert cannot, which is why they are harder and more useful.
