Sample Questions
Question 1
Easy
For a portfolio of claims, R reports that the 90th percentile of claim size is 12,400. Which interpretation is correct?
🎉
Correct Answer: B
Solution
B is correct. The 90th percentile is the value below which about 90% of the observations fall; equivalently, about 10% of claims exceed it. It is a position in the sorted distribution, not a count of ties, an average, or a fraction of the maximum.
Question 2
Medium
Which pairing correctly matches a data source to its type?
🎉
Correct Answer: E
Solution
E is correct. MRI scans are images with no inherent row-column schema, making them unstructured. The premium spreadsheet, GPS coordinate columns, and coded diagnosis table are all structured tabular data, and recorded audio files are unstructured (not structured), so only the MRI pairing is stated correctly.
Question 3
Hard
A candidate labels a column as 'discrete' and another column as 'ordered.' Which pairing correctly matches variables to those labels?
🎉
Correct Answer: D
Solution
D is correct. Number of prior claims takes gapped integer values, which is discrete, and a graded credit rating (A > B > C > D) is a categorical variable with a meaningful rank, which is ordered. The other pairs mislabel continuous quantities as discrete or nominal labels as ordered.
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.
