Thanks

I really appreciate you sending me these test questions as I’m getting back into the groove after being out of it for five years. I appreciate what you guys are doing.

Response from developer

Thank you for sharing that with us! We’re honored to be part of your journey as you get back into studying after five years away. Taking that step can feel challenging, and we’re glad the practice questions are helping you build momentum and confidence again. We truly appreciate your support, and we’re cheering you on every step of the way! 💙📚

Love this App!!

I got this app right before my exam. I set my goal to get a 90% and to get really hard questions. I passed my exam with a 90%. This app is amazing. I love it!!!

Response from developer

That’s amazing, huge congratulations on passing! 🎉 We love hearing that you set a high goal, challenged yourself with the hardest questions, and saw it pay off on exam day. That kind of focused prep and determination makes all the difference. Thank you for trusting the app right before your exam, and we’re so glad it helped you walk in ready. Well done!

It could be better

The subscription is very expensive. Also it repeats similar questions too many times, especially when answered correctly multiple times. It would be better if app gave me an option to focus on weak area ( the question that were incorrect ) as well including more new question in daily quiz. Out of all the CST prep app, it is decent app.

Response from developer

Hi, thanks for the thoughtful feedback and for calling the app decent, we appreciate that. A few of the things you mentioned are actually features already built into the app. You can focus on weak areas using the Missed Questions Quiz, which lets you retake only the questions you answered incorrectly. Our analytics and stats also highlight weaker categories so you know exactly where to focus your studying and work on specific areas. You can also adjust the difficulty if you find the questions are repeating and they're not updating fast enough. We’ve also continued expanding the question bank and improving the daily quizzes so users see more variety. If you’d be open to exploring those features, we think they may address the concerns you mentioned. And if the app has been helpful overall, we would truly appreciate you considering updating your review. Future CST students rely heavily on those reviews when choosing study tools. If you ever need help finding these features or these don't address them please reach out to us at support@eztestprep.com and we’d be happy to help.

Cancellation

The app itself is pretty good. It tends to ask the same questions over and over though. My rating comes from the difficulty canceling the subscription when no longer needed.

Response from developer

We're glad you enjoyed the app! Our questions are dynamic and can repeat if the app feels you're struggling with a specific topic or subject. Thank you for letting us know about the cancellation. We're currently updating this process to make it easier and more intuitive. If you need any help at all with cancelling, please reach out to us at support@eztestprep.com

best CST app i’ve tried!!

I haven’t taken my 2nd attempt on the CST exam yet, but this app has been helping me so much already. The UI is clean and really user friendly, which makes studying way less overwhelming. The questions feel very similar to the actual CST format, and I love that it explains the right answers clearly so I can actually review (you can bookmark questions too and it has a separate category for the things you’ve gotten wrong and you can retake them again altogether). There’s progress checks and a level up system to keep me motivated, and daily reminders that help me stay consistent even on busy days or when i’m just laying down. I’m definitely starting to feel more confident with every practice quiz. The app covers everything from the AST outline (like perioperative care, basic science, pharmacology, microbiology, and anatomy) so I don’t feel like I’m missing anything important. Overall, it’s been an amazing study tool so far!

Joynal

Good customer service.

Response from developer

Thanks Joynal! Glad we were able to help!

Joynal

This app doesn’t give any easy options to cancel your subscription. It will still your money.

Response from developer

Hi Joynal, We're sorry you felt that way, but I can promise you we don't steal (or still) your money. We put easy instructions and links on how to cancel your subscription in the app settings, in the FAQs, in the Contact Us, on our website (eztestprep.com), and in the app description. We also answer emails at support@eztestprep.com and are always happy to help you cancel or adjust your subscription. But we appreciate you letting us know here instead of reaching out.

Helpful!

I downloaded this app a month before re-taking the certification exam (last took it in 2018). It was very helpful to remind me what to prep for.

Response from developer

Hi Whitney, We're so glad we were able to help you retake the exam and congratulations on passing! Thank you for taking the time to leave us a 5 star review and best of luck with your recertification!

Wrong answer

The question is, what drug is used as an antidote for opioids, and your test has the CORRECT answer as flumazenil, even though the explanation says Naloxone as the correct drug to use.

Response from developer

Thank you for taking the time to let us know. We actually have a button on every question where you can let us know if you find a mistake in a question and our editors fix it immediately. Our editors have updated this question to make sure it is correct and you can update your app to see the adjustment. We would also love to offer you a free next subscription for taking the time to let us know about the question. Please reach out to us at support@eztestprep.com. Thanks!

So helpful!!!! 😍

I’ve been using this once a day for the past few weeks and feel way more confident than I was. Wish me luck next week on my exam!

Response from developer

Thanks for taking the time to let us know you're enjoying the app and best of luck on your exam next week!

One star rating because the app is functional but broken. Developers promised to fix and didn't

Update, they claim to have addressed my issue. I waited for that update to post my first review

And that's the problem. The cosmetic update didn't fix the core issue.
I did see the changes, but the question feed system is still broken. I counted the total questions myself, over a 60 day period, on max difficulty, nowhere near "1100", generously, my count is close to 600.

The questions are constantly repeating and the promised number of 1000 isn't true! Ridiculous and too expensive for such a simple app, that doesn't WORK!

Response from developer

Hi Josh, we're incredibly sorry you aren't happy with the app. I believe we fixed what you emailed in about. We also have 1100+ different questions on this app. However, the questions are dynamic, meaning they will increase or decrease in difficulty as you progress, so it is possible to see similar questions because of this. Please let us know if there is anything we can do to make it better or help with your studying.

Expensive and lots of bugs

I’m pretty disappointed. I expected pretty top tier study help for $65, so far I’ve found questions that I got right but the wrong answer is marked correct and confirmed my correct answer in the explanation. In another my answer was wrong because I used cc instead of ml, but they are the same thing. Work the bugs out if you want that much money

A useful tool to master your CST exam

As a surgical technology student gearing up for the Certified Surgical Technologist (CST) exam, I was in search of a comprehensive study aid to help me prepare effectively. The CST Tech Prep App proved to be an invaluable resource, offering a range of features tailored to enhance the study experience.

One of the app's most notable features is its organization by category, which allows users to focus their study efforts on specific areas of the CST exam, such as anatomy and physiology, surgical procedures, and sterile technique. This categorization ensures thorough coverage of all exam topics and facilitates targeted review.

The inclusion of quizzes within the app provides an interactive way to assess knowledge retention and gauge readiness for the exam. With customizable quiz options, users can tailor their practice sessions to focus on areas where they need improvement, maximizing the effectiveness of their study time.

Daily progress tracking is another standout feature, providing users with insights into their study habits and allowing them to monitor their advancement over time. This feature not only promotes accountability but also serves as a motivational tool, encouraging users to stay consistent with their study routine.

The app's reminder functionality ensures that users stay on track with their study schedule by sending regular prompts to review materials. This feature is especially helpful for busy students juggling multiple responsibilities, helping them maintain momentum in their exam preparation efforts.

The integration of completion badges and goal setting adds a gamified element to the study process, motivating users to strive for mastery and progress. Achieving milestones and reaching study objectives becomes more rewarding with these motivational tools in place.

Overall, the CST Tech Prep App is a comprehensive and user-friendly study aid that empowers aspiring surgical technologists to excel in their CST exam.
