About this app

So, you’ve chosen a career where you pass sharp objects to over-caffeinated surgeons, keep the sterile field from becoming a biohazard, and make sure no one leaves a clamp inside the patient. Good choice. Now it’s time to conquer the CST exam.


That means diving into anatomy, memorizing more surgical instruments than a med student on 'caffeine' pills, and mastering sterile technique like your certification depends on it, because it does. Fortunately, you don’t need to suffer through dusty textbooks or forums run by someone’s cousin who “totally passed last year.”


EZ Prep’s Certified Surgical Technologist (CST) Study App is the fastest, smartest, and least soul-crushing way to prep for the NBSTSA® exam. Built for future techs who are already knee-deep in the OR grind, our app gives you everything you need to pass, without the fluff, filler, or fear.


Whether you're at clinicals, hiding in the locker room, or mentally recovering from a 6-hour orthopedic case, you can study on the go with expertly written questions, straight-to-the-point explanations, and a platform that still works even when the OR lounge Wi-Fi gives out.


Built by actual CSTs and surgical educators (not bots or bored anatomy majors), all content follows the 2026 NBSTSA® guidelines, so you’re reviewing what actually matters, not just guessing what surgical pharmacology might mean under pressure.


Exam Topics Covered Inside:


Preoperative Preparation – From gowning and gloving to avoiding an infection control disaster


Intraoperative Procedures – The art of passing instruments and keeping your cool in the splash zone


Postoperative Procedures – Cleaning up without screwing up


Administrative & Personnel – Chain of command, ethics, and not getting fired


Equipment Sterilization & Maintenance – Because a rusty scalpel is never the right choice


Anatomy & Physiology – Know your organs, or get called out by a very loud surgeon


Principles of Microbiology – Bacteria: tiny, terrifying, and on the test


Surgical Pharmacology & Anesthesia – What goes in, what knocks them out, and what you better not mess up


App Features That Won’t Break Sterile Field:


• Adaptive Difficulty – If you're crushing it, we make it harder. If you're struggling, we dial it back

• Full-Length Practice Exams – Just like the real deal, minus the sterile gloves and existential dread

• Progress Tracking & Study Goals – See your score climb faster than a surgeon’s blood pressure when the cautery fails

• Instant Feedback – No guessing, no delays, just clear explanations you’ll actually remember

Ratings and reviews

Someone previously mentioned it's the same questions over and over. That is exactly correct despite being told it's Dynamic. It's the same 'group' of questions repeated over and over on the free version.

This app was good to a certain point. It did not cover all the categories required for the test. It had a tendency to repeat the same questions over and over again. I would say it covered maybe 25% of the test topics. I was retesting with 12 years experience and in no way for the amount of money I paid each month to study on this app was it worth it. It was a good lesson to not to let my certification lapse again. Disappointed with this app.

They only show you the questions they want. I studied the same 100 questions over and over and over.
