About

WHAT'S INSIDE
• 40 lessons across 9 units: perioperative care, instrumentation, sterile processing, A&P, microbiology, and surgical pharmacology
• 1,600+ multiple-choice questions with rationales
• 1,500+ flashcards for instruments, counts, positioning, and OR workflow
• Mini tests, unit drills, and a timed 150-question, 4-hour exam simulator
• Scoring against the 98/150 pass line used on the real exam
• Save missed questions and review weak domains
HOW YOU STUDY
Start with a diagnostic, then work through lessons. Practice in short 25-question sets or sit a full-length simulator. After every test, review what you missed with explanations — not just a score.
