Yes. Every multiple-choice item carries a written rationale that states the controlling principle behind the correct answer and then addresses each wrong option in turn — why it tempts and precisely where it fails. Knowing why the plausible answer was wrong is worth more than knowing which letter was right.
It is organised into 4 chapters that follow the published exam blueprint: Economic Factors and Business Information; Investment Vehicle Characteristics; Client Investment Recommendations and Strategies; Laws, Regulations, and Guidelines, Including Prohibition on Unethical Business Practices.

Last reviewed 2026-08-22. Banks are written against the certifying body's published exam outline and re-checked when that outline changes — exams get renumbered, retired and reweighted, and a bank written to a superseded outline teaches the wrong proportions. Figures that are re-indexed annually are deliberately not asserted as rules; the questions test the governing principle instead.
This bank is written against FINRA's published exam material. Check the FINRA exam content outlines for the current outline, fees and eligibility rules — those change, and the certifying body is the only authority on them. CoStudy is not affiliated with FINRA.
