Exam-by-exam breakdown
How Achievable and Securities Training Corporation (STC) stack up for each exam, from our research dossiers and the published CHART scores.
Achievable costs less, gives a year of access, and its SIE practice runs hard in the right way. STC's base tier is pricier and its guarantee only starts at Premier, but the finals reputation and all-tier instructor hotline are real. Self-study first-timers lean Achievable.
Series 7
All Series 7 prep courses →STC's practice finals are the readiness benchmark candidates measure against on the 7, and its top tier adds live classes. That authority costs several times Achievable's price. Achievable fits budget self-studiers; STC fits candidates whose firm treats it as the standard.
Series 63
All Series 63 prep courses →For a short law exam, Achievable's price and guarantee make it the simple pick. STC's strengths, live classes and benchmark finals, matter least here.
Series 65
All Series 65 prep courses →Candidates repeatedly name STC among the most representative practice for the 65, and the instructor hotline helps with law-heavy confusion. Achievable is cheaper with the gentler textbook. Retakers who need confidence in the final mile lean STC.
Series 66
All Series 66 prep courses →STC's realism reputation carries to the 66, and its mid tier bundles the refund guarantee. Achievable remains the budget pick, with longer access for the corequisite path.
