ActuaryProof is an English-language actuarial exam study publication published by Fermion Co., Ltd. It provides independently written, calculation-checked solutions and original practice problems for candidates studying from official sample-question sets.

One reference, one durable explanation
The free library is organized by exam, syllabus topic, and official sample reference number so that a candidate can move from the source question to the relevant explanation without searching through a general course.
Each published problem page identifies the exam and sample-question number, states the mathematical approach, shows the solution in visible steps, discusses wrong-choice mechanisms where they can be identified, and includes an original worked variant. Topic and exam hubs connect those references into a study path.
Paid manuals compile the same verified records into searchable, syllabus-ordered PDFs. A purchase is a one-time digital purchase, not a subscription. Delivery uses Stripe Checkout and a secure download service; the buyer email is stamped into the personal-use PDF.
Editorial standard
What “verified” means here
Verification is a defined publication gate, not a claim of official status.
Independent writing
Solutions and variants are written as original explanations. Official question wording is not reproduced while permission has not been granted.
Reproducible calculation
The displayed answer must follow from a recorded computation and agree with a proportionate independent check.
Official-key agreement
The result must select the published official answer letter. A disagreement is withheld from publication until it is resolved.
Rights and output check
Finished web pages, data, variants, and product PDFs pass an automated source-text overlap check before release.
Rights boundary
Independent, not official
ActuaryProof is not affiliated with, endorsed by, or sponsored by the Society of Actuaries. 'SOA' and exam names are used solely to identify the exams for which these study materials are relevant. All solutions and variant problems are original works.
Official problem PDFs remain at their official source. ActuaryProof pages refer to a question by exam and number while presenting our own explanation and practice material.
Study boundary
No exam-outcome promise
The library is a worked-solution reference. It does not guarantee a passing score, predict a candidate’s result, or replace the current official syllabus, rules, or source questions.
Readers should confirm current exam requirements with the relevant official source and report any suspected mathematical or rendering error through the correction process.
