NBSTSA's Certified Surgical Technologist app is a powerful examination simulator that allows you to create customized practice tests with detailed answer explanations for every question. View your results and examination history with just a few taps. Study anywhere at any time without Internet.

The app utilizes the “spacing effect” to enhance your learning capability. You’ll space out your studying into shorter, more productive study sessions, which allow your brain to retain more information. Simply tell the app how many questions you want to take, enable the timer, and filter examination content to create the perfect study experience.

It was just OK...

I memorized all the questions and answers within a couple months. When i took the CST practice exam in our program i passed it with flying colors bc the majority of the questions from the app were on there. When it came time for the CST exam, i believe only like 3-4 questions from the app were on my exam. The questions on the exam were a lot more difficult than the ones from the app. Would i get it again? Yes, only bc it did teach me a lot of things with explanations. Some explanations were good, others just repeated the answer. Do not rely on this app to pass your exam!!

Test taking techniques

Love this app. I learned to read questions thoroughly and picked up on key points. Learned to problem solve the answers to get the correct answer. When reviewing my text books I am able to learn more cause I know now the type of questions that are given. You can quiz on a mixture of subjects or focus on a particular one.

CST Exam

I get severe test anxiety so I wanted to be as prepared as possible for this exam. I liked the test questions, they were well rounded and gave me a ‘feel’ as to what to expect. This definitely helped because I was able to pass my CST exam the first try!! I would definitely recommend this as a tool to study from!!
