Official NBSTSA CST Exam Prep Customer Insights

1. So im locked out!Find the same questions for free on quiz let...I cant believe I wasted time on this app and its basically just an ad to get you to spend $40 on very few questions.. it's like if they made the base app added a few things and then gave up on it... it's too expensive for what it is... your better off using the free stuff.. you'll get the same out of it and get to keep the 40.My big issue with this app is that I actually paid 40 dollars for it on 12/1/15, but ended up not taking the test because certification isn't required in my state.

2. So I decide to go ahead and get certified, I go back into the app, and it wants me to pay 40 dollars to "unlock premium." When I go to restore purchase it says there's not purchase history, but I can go in my purchases and see where I already paid 40 for it.

3. The premium ia well worth it.Downloaded app with hopes of taking test, but just the same old.questions. No new material.

4. Very frustrating!!!I signed up and paid the money for the questions.

5. When i click on 'forgot password' it takes me right back to the sign up page! Ive deleted and redownloaded the app a fee times and i keep getting the same issue.

6. I understand but mostly students would be using this app so that isn't well thought out.A great way to study and practice the test.

7. You get 330+ questions for the money, all fairly generic and easy, and all you'll burn through fairly quickly.

8. Looked at the new version and they are not offering what I paid for to study.

9. Definetly recommend this app to everyone and everyone preparing for the test!I can not open the app that I have already installed.

10. Thought there would be more available without having to pay so you can't get anywhere unless you pay money.

11. I'm glad to say I passed my CST in Aug 29 and this app helped me to better understand concepts as relate to our career.
