Expert take: what CAS Exam 8 really tests
CAS Exam 8 is the advanced pricing exam of the Fellowship track — classification ratemaking, GLMs, increased-limits and excess pricing, individual risk rating, and catastrophe and reinsurance pricing. It is a 4-hour, calculation- and essay-heavy exam graded 0–10 (6 to pass) and builds directly on Exam 5.
Preparation tips
- Get truly comfortable with GLMs — they are the largest single topic and appear throughout.
- Practise increased-limits / excess-layer and individual-risk-rating calculations until they are automatic.
- Use past papers to internalise the multi-part, applied question style.
Common mistakes to avoid
- Treating catastrophe and reinsurance pricing as afterthoughts because they are lower-weight — they still supply pass-margin points.
