Canadian Securities Course (CSC) — Exam 1 & Exam 2 newly revised

Our CSC Exam 1 and CSC Exam 2 question banks were recently revised end-to-end to closely match real exam requirements: MCQ-only (MSQ question types removed), around 250 learning objectives, and close to 20 distinct exam-style question patterns. We also calibrate difficulty and timing distributions (psychometrics) so a prepared candidate should rarely need more than 2–3 minutes per question. Not trivia. Not puzzles. Practical decision-making under time pressure.
