The CAS publishes past exam papers, examiner's reports (model solutions with common errors) and pass marks for its upper-level exams. Actuarium does not reproduce copyrighted papers; use the official archive below and the practice set on this page, which is original and written in the same style.
Sittings worth mining
Fall 2018 – Fall 2023
Released papers show heavy weighting toward Bühlmann–Straub and Bayesian conjugates.
2024 onward
Content outline emphasizes statistical learning; expect more tree/boosting conceptual items.
Recurring question patterns
- A full Bühlmann–Straub computation from raw exposure/claim data.
- Posterior mean or predictive probability from a conjugate pair.
- Interpretation of MCMC diagnostics or a Gibbs step.
- Bias–variance or tuning-parameter reasoning for lasso, random forests or boosting.
The practice tab reproduces these patterns with original numbers — work a pattern here, then confirm against the official paper.
