Actuarial Empire


When we formed Actuarial Empire, it was with the desire to create a superior study guide for the exam while at the same time being more affordable and accessible for people still in school. We have stayed true to this vision. Our materials are priced competitively and are loaded with hundreds of examples and practice problems to explain the concepts presented. It is our hope that the resources provided in our book and the website will greatly help you in the pursuit of your FCAS or FSA designation.
