Level 1 · Warm-up
1 How many lines does an error-log entry have?
Show worked solution
Five. The question, your answer, the correct answer, WHY you got it wrong, and your specific fix plus re-test date.
2 You scored 100% on a practice test. What did it teach you?
Show worked solution
Nothing new. The learning lives in the questions you get wrong — that is where the marks are hiding.
Level 2 · Core
3 You could state the definition of osmosis but explained a diagram using it backwards. Which type of mistake?
Show worked solution
An understanding gap — you knew the what but not the why. Fix by re-learning the mechanism and explaining it aloud.
4 Line 4 of your log says "silly mistake". Why is this entry wasted?
Show worked solution
No diagnosis means no fix. Write what you actually did: "used the perimeter formula for area."
Level 3 · Challenge
5 Your logged errors are spread across many topics but nearly all occur in the last quarter of each test. What is the real problem?
Show worked solution
The pattern is positional, so the fix is pacing and stamina — timed full-length practice, not more content revision.
6 You diagnose an application gap and fix it by re-reading the chapter three times. Why will this probably fail?
Show worked solution
The content was never the gap. An application gap needs varied, interleaved practice so you rehearse choosing the method.
