## Most critical reviews (10 lowest-rated)

### 1/5 — Glitches galore

*2023-02-05, version 3.3.0*

Wasted $100 on this app!

### 1/5 — Terrible app, just another money scam app.

*2022-06-29, version 2.1.2*

The previous NBSTSA CST app had a load of different features including personalizing the test, and better questions. I’ve taken already 10 different test on this app and so far I’ve seen repeated questions on every test. I would give this app zero stars if I could.

### 1/5 — Not correct

*2022-05-20, version 2.1.1*

has told me multiple answers are incorrect with the explanation saying that my answer was correct and it still counts it wrong, many things are misspelled or improperly worded. Will no longer be using the app, do not recommend.

### 1/5 — No CST exam

*2022-01-12, version 2.0.2*

Why is this called AST CST if there are no questions to study for the AST CST exam? False advertisement, deleting now..

### 1/5 — Don’t support CST Exam

*2021-10-18, version 2.0.1*

Does not have the Certification exam for surgical technologist. Deserves less than 1 star.

### 2/5 — Same questions over and over…

*2022-07-22, version 2.1.2*

There are about 40 to 50 questions and they are all the same.

### 2/5 — Needs to be Proofread and Edited

*2022-04-26, version 2.1.1*

It’s an okay app with okayish questions (CST prep) but there are typos in every single questions and a lot of questions and answers are written to be easily understood.

### 3/5 — Tests

*2024-06-19, version 3.3.2*

The information is useful the only issue I’ve had with the two days of use is that within the 10 tests I’ve taken I’ve put the correct answers down and I should get about and 80% but when I submit the test I only get about a 50% and the reason why is that after I’ve submitted the test my answers get changed to something entirely different when I had originally tapped the correct answer other than that I haven’t had many issues.

### 3/5 — CST is available now

*2022-04-01, version 2.0.2*

So they do have CST on this app as of 3/31/2022 but I will say the questions it’s like you know it’s only one answer the other answers aren’t even close to relating to the question smh!!!! I paid so I’ll be practicing with this until I take my test a month from now but only using a month subscription and will be canceling after that

### 4/5 — CST

*2022-11-10, version 3.3.0*

There should be an iPad version of this app. Other than that it’s good

## Most praised reviews (2 highest-rated)

### 5/5 — Acting like I have never paid full price before

*2022-08-28, version 3.0.0*

Purchased the app a while back and it has not transferred to this new app

### 5/5 — 100% useful!

*2022-05-14, version 2.1.1*

I'm so glad I passed my exam! I prepared for a very long time and hard but I got the result from my efforts! the app proved to be very useful...rated it 5!
