What the questions look like

Every question in the free Series 24 bank carries a full worked solution. Here is one from the pool:

Question 1 Medium
Under FINRA Rule 5240, a principal supervising market makers must prohibit each of the following EXCEPT:
Solution
A is correct. FINRA Rule 5240 prohibits three kinds of conduct. A member may not coordinate quotations, prices or trades with another member. It may not direct or request another member to alter a price or quotation. It may not threaten, harass, coerce or intimidate another member to influence its quotes or trading. A market maker that independently decides to change its own bid in response to public market conditions, including a competitor's displayed quote, is engaged in ordinary competitive pricing. The rule does not reach that conduct, so the principal need not prohibit it.

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 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 41 exams with more than 48,000 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.
