Every question in the free MAS-II bank carries a full worked solution. Here is one from the pool:

Question 1 Medium
Compared with bagging, random forests are MOST LIKELY to improve out-of-sample predictive accuracy primarily because they...
Solution
E is correct. Bagging averages predictions from trees fit to bootstrap samples, which by itself only modestly reduces variance because the trees remain highly correlated. The trees tend to share top-level splits on the same dominant predictors. Random forests restrict each split to a random subset of predictors, which forces the trees to diverge and lowers the pairwise correlation between them. Because the variance of an average of correlated predictors depends on that correlation, the decorrelation step lowers ensemble variance below what bagging achieves.

About FreeFellow

Jeffrey Ting, founder of FreeFellow
Jeffrey Ting
FSA, CFA · Founder

FreeFellow was built by Jeffrey Ting, a credentialed actuary and CFA charterholder who passed thirteen of the hardest exams in finance on the first attempt, and paid four-figure prep fees for every one. The learning itself was always free. The price was a moat.

So he started writing his own questions, then lessons, then mock exams, until it grew into a full prep platform covering 40 finance credentials with more than 44,000 original practice questions. The name says exactly what it is: the question bank is free, and Fellow is what you become once you pass.

01
Cost shouldn't decide who gets in.

The exam is a fair gate. A four-figure prep course is not. FreeFellow takes the second gate down, so the exam is the only one left.

02
Free should mean free.

No trial clock, no email gate, no credit card. The question bank, worked solutions, lessons, and readiness score stay free, and they are enough to pass.

03
Built by someone who sat where you sit.

He paid for the big-name courses, found nothing he respected, and built the prep he wished had existed. Not a marketing team that has never sat an exam.
