### 1/5 — Out of date. Refund Requested

*2021-07-24, version 4.1*

The information in this app expired in 2019. Don’t buy!

### 5/5 — CDL DMV Texting App.....

*2020-11-06, version 4.1*

This app is GREAT in helping you prepare fir all of your California CDL/DMV/Class A written test.

### 1/5 — Not Happy

*2018-11-08, version 4.0.10*

I paid for this CDL Manual; Then when received it; it’s outdated; it’s a 2015 manual ; it is now 2018 and a few months it’s going to be 2019
I want my manual to be the currant year, I won’t be buying anything from this site ever again.

### 4/5 — It worked fine

*2016-01-31, version 3.1.1*

Once I learned how to use it, I became very satisfied. I thought the app covered what's in the California CDL handbook very well. And I passed on my first try!

### 5/5 — Well worth the $

*2015-12-15, version 3.1.1*

Great App. Well worth the $10. This is all I used to study for my Class A with endorsements. Passed everything on the 1st try.

### 1/5 — So NOT worth the $9.99

*2015-09-26, version 3.1.1*

I was ready to go give the CDL tests at the local California DMV I was very confident I would pass, but to my huge surprise NONE of the questions from this app appeared on the tests NONE, I'm very very much disappointed and very much angry Having spent 9.99 and my valuable time,  I wish I can get my money back 😠 My personal advice to anyone out there DO NOT PURCHASE this app 👎🏽

### 5/5 — This is the best

### 1/5 — confusing app

*2015-03-29, version 3.1.1*

### 4/5 — Nice app

*2015-02-28, version 3.1.1*

Just bought it to take my tank endorsement test. I passed, but there were a couple of questions I had that weren't on the app. Overall a good app.

### 5/5 — Great

*2015-02-05, version 3.1.1*

Me and my wife are going for our CDL class A and just reading the DMV book just wasn't cutting it. So i found this app and it helped a lot. Keeps track of all your score. I started out low and now im scoring in the high 90% on pre test with over 400 questions. I feel more confident taking the written test at DMV
