### 2/5 — Inaccurate

*2014-01-24*

I'm an instructor, some good stuff on here but it's not all accurate I.e question about parallel parking it's says has to be done within 1.5 car lengths when actually it's about 2 car lengths according to the DSA. In hindsight there were other questions with which I thought the answer given was incorrect.

### 5/5 — Fantastic

*2013-12-12*

Brilliant revision tool. I passed first time using this app. Much easier than trying to wade through books. 
The questions are exactly the same word for word as asked in the test. 
Very pleased! Thankyou.

### 5/5 — Brilliant app

*2013-06-04*

I do a mock test every day and I find this helps enormously. Am about to take my part one and already am averaging 100% most of the time. Would highly advice anyone to buy this if only to gen up on rules and regs.

### 5/5 — Great app

*2012-11-14*

Great app, has all the questions you'll be asked in your part 1 test. Passed first time with it today, so thought it deserved a review. My only negative point is the slide bar to pick the amount of questions you want to answer. Very fiddly, takes a while to get the number you want. Other than that, worth the money!

### 5/5 — Fantastic App

*2012-10-19*

Brilliant app!! I used this to get me through the ADI theory test and passed first time. The questions are worded exactly the same as the actual test. I would still recommend buying the text books as learning the bank of questions alone isn't enough especially for the second and third parts. Would 100% recommend though.

### 5/5 — Highly recommended!

*2012-10-09*

I just passed my theory test today, highly recommended if someone wants to save money and time this is the best app.
Thanks

### 5/5 — Very good for practice at home or out

*2012-08-08*

Great app. So easy to use & you can pick it up for a short go or much longer. Helps it all go in.

### 5/5 — Excellent app

*2012-07-19*

I passed my theory first time today, the app is well worth the money easy to use and the questions are the same as the test!! You can't fail if you know these questions! Except for the hazard perception, I got 59 and just passed it after getting 0 on one clip for clicking too many times!!! STUPID hazard perception!!!

### 3/5 — Adi app

*2012-05-14*

Overall it is a good app, but when you want to pause the practice there are no functions, you have to start all over again. Also at the mock test at the end it will not tell you the questions not answer correct what band group they were, and whether you fail or not. Some improvement needed.

### 5/5 — Excellent app

*2012-04-18*

Would recommend to all, easy and simple to use. 
