Understanding actuarial assumptions is a vital skill for anyone preparing for the Society of Actuaries (SOA) preliminary exams, especially Exam P (Probability) and Exam FM (Financial Mathematics). These assumptions form the backbone of actuarial models used to price insurance products, assess risk, and make informed financial decisions. If you’re gearing up for these exams, getting comfortable with how actuarial assumptions work—and how to apply them practically—will not only help you pass but also set a strong foundation for your actuarial career.
