Recurring question patterns
- Every question is self-contained; there is no partial credit, so speed and formula recall dominate.
- Expect deductibles, policy limits, and 'per loss' vs 'per payment' framing even on Exam P.
- Distractors are usually the result of one specific slip (wrong tail, forgetting a conditional, wrong compounding).
The practice tab reproduces these patterns with original numbers — work a pattern here, then confirm against the official paper.
