Browse all 461 active Financial Mathematics (FM) Exam sample references by number or syllabus topic. Every page gives a step-labeled solution, a separate calculation check, wrong-choice analysis, and a fully worked original practice problem. Official question wording remains withheld.
Current official set
The official sample set retrieved 2026-07-30 contains 461 active questions numbered 1–462. 1 question SOA has deleted is excluded. Every remaining question has a worked solution here.
Keep the official wording in its source document and use this library as the worked-answer layer.
Open the official sample-question PDF, find the same number, and commit to an answer before reading the solution.
Check the named model, event or comparison date, parameter convention, and the exact step that selects the answer letter.
Use the distractor notes to identify whether the miss came from modeling, timing, boundaries, units, or arithmetic.
Prove that the method transfers to new wording and parameters, then return to the topic hub for the next reference.
The Society of Actuaries also provides a free randomized online sample exam for P and FM using its existing sample-question pool.
