### 2/5 — Not reliable

*2017-10-24, version 4.0*

This app is very useful but isn’t a great source. I actually have the official NYC CDL cheat sheets. The question and answer are not the same. This app wouldn’t be reliable if you were studying for the NYC exams. I wouldn’t say this app is a waste of money but it’s not worth $10. There are free apps available. Good luck.

### 1/5 — Run

*2017-09-27, version 4.0*

Do not buy this app!

### 5/5 — No está en español

*2017-06-16, version 4.0*

Please español

### 1/5 — Not worth the money.

*2015-07-30, version 3.1.1*

This app is over priced doesn't help much. I got another app for 2.99 that has help me a lot more.
Do not buy it not worth it.

### 2/5 — Wow

*2015-04-28, version 3.1.1*

I studied this app religiously for 3 weeks before I went to take my cdl permit test. Failed. Have the questions they asked at the dmv didn't even come up in this app. I wish there was a refund button instead of a "rate me" button.

### 1/5 — Pitiful (don't buy this app)

*2015-03-11, version 3.1.1*

This app is a pure rip off. It's a collection of widely available public information. It doesn't "teach" you at all. It contains literally just the CDL manual and practice tests. Which you can find for absolutely free online. I bought this expecting it to tell me which subjects I needed work in, what exactly I need to know to pass the Class A, B, C, etc. CDL tests, and constantly train my knowledge of the material. This does none of that and nothing beneficial. I got it to have a teacher because I'm horrible at teaching myself, and it failed miserably. It is nothing but a bunch of slopped together, poorly organized public information. I highly advise not buying this.

### 5/5 — Worth it!

*2014-12-06, version 3.1.1*

I've been trucking six years with dry can experience only. Took my X endorsement test on 12-5-14 and passed, I give all credit to this app. 95% of the questions in this app are on the real test. I studied this app earnestly for 3 days until I memorized the 120 questions in Tanker and Hazmat. The day before my test I went online and did free practice tests that filled in a few blanks this app did not cover. I would highly advise downloading some images of the placard system, the HMT table (how the columns are ordered), hazmat shipping papers, and the hazmat tables (2 of them). Also know the basic difference between the HMT, Appendix A (reportable quantity) and Appendix B (marine pollutants). I only had to guess maybe three times throughout the entire 50 question test. (20 tanker, 30 hazmat)

### 5/5 — Amazing

*2014-09-24, version 3.0.2*

Amazing app really easy to study been studying, the bad thing now is that I upgraded to iPhone 6 with iOS 8 now I can't look at the study guide please help any updates coming soon?

### 5/5 — Luv the app

*2014-04-15, version 3.0.2*

If it was not for this app I would not have gotten my class a with all endorsement great study aid better than the book it self

### 2/5 — Difference

*2014-02-12, version 3.0.2*
