Sample Questions

Question 1 Easy
Which of the following is a property of a coherent risk measure?
Solution
A is correct.

Subadditivity is one of the four axioms of coherent risk measures (monotonicity, positive homogeneity, translation invariance, subadditivity).
Question 2 Medium
Which of the following statements about TVaR is FALSE?
Solution
B is correct.

TVaR0=E[X]\text{TVaR}_0 = E[X], while VaR0\text{VaR}_0 is the minimum possible value (often 0 for loss distributions). Since E[X]E[X] generally does not equal the minimum, the statement that TVaR at level p=0p = 0 equals VaR at level p=0p = 0 is false.
Question 3 Hard
The number of claims NN follows a zero-truncated Poisson distribution with λ=1\lambda = 1. Calculate E[N]E[N] and Var(N)\text{Var}(N).

You are given: e−1=0.36788e^{-1} = 0.36788.
Solution
D is correct.

For a zero-truncated Poisson with parameter λ=1\lambda = 1: E[NT]=λ1−e−λ=11−0.36788=10.63212=1.582E[N^T] = \frac{\lambda}{1 - e^{-\lambda}} = \frac{1}{1 - 0.36788} = \frac{1}{0.63212} = 1.582. Var(NT)=E[NT](1+λ−E[NT])=1.582(1+1−1.582)=1.582×0.418=0.661\text{Var}(N^T) = E[N^T](1 + \lambda - E[N^T]) = 1.582(1 + 1 - 1.582) = 1.582 \times 0.418 = 0.661. Alternatively: Var(NT)=λ(1+λ)1−e−λ−(λ1−e−λ)2=20.63212−(1.582)2=3.164−2.503=0.661\text{Var}(N^T) = \frac{\lambda(1 + \lambda)}{1 - e^{-\lambda}} - \left(\frac{\lambda}{1 - e^{-\lambda}}\right)^2 = \frac{2}{0.63212} - (1.582)^2 = 3.164 - 2.503 = 0.661. The answer is E[NT]=1.582E[N^T] = 1.582, Var(NT)=0.661\text{Var}(N^T) = 0.661.

FSA, CFA · Founder

FreeFellow was built by Jeffrey Ting, a credentialed actuary and CFA charterholder who has passed thirteen of the hardest exams in finance, all on his first attempt. He paid four-figure prep fees along the way.

So he started writing his own questions, then lessons, then mock exams, until it grew into a full prep platform covering 40 exams with more than 45,000 original practice questions.

01
Cost shouldn't decide who gets in.

A CFA charter, a CPA license, an actuarial credential. Each opens a real career, but prep fees add to the cost of getting there. FreeFellow keeps its original question bank and written lessons free so you can study even if a paid course is out of reach.

02
Free should mean free.

The original question bank, the worked solutions, the topic lessons, mixed practice, and your readiness score stay free, forever. Full access needs a free account, and practice usage limits apply. Fellow adds AI grading on supported exams, spaced-repetition flashcards, full-length mock exams, analytics, and a study plan that adapts to your progress.
