The App would be perfect if we could report wrong questions

by Irritable.

I used this app to pass everything except passenger and HME (because I haven’t taken them yet). I’m currently studying my hazmat and I noticed a question I got wrong and I didn’t think I was wrong. So I went and read the section of the manual (which I have printed out, highlighted and noted to heck and back) and sure enough the app was wrong. This wouldn’t be such a big deal if we had a way to report it. And on the other endorsements it’s not as much of a problem. But the hazmat test is difficult enough on its own. We don’t need to be fed wrong answers. Without a way to report these incorrect answers to the dev, this app is a one star for me.

At least one of the questions is inaccurate

The question that says: You are unloading students along your route. Where should students walk to after exiting the bus? The correct answer is: ‘Tell Students to exit the bus and walk at least 10 feet away from the bus to a position where the driver can plainly see all students.’ Taken from section 10.2.3 from the VA DMV CDL manual. Your app states that 15 feet is the correct answer and says it’s in 10.2.5 which is incorrect. I would’ve suggested this edit in the app if I were given the option to do so. Please edit to give the correct answer.

Needs updating

There are several questions on the exam that are not on this app. I would estimate this app has about 85% of the questions I encountered on the test. I was able to pass GENERAL KNOWLEDGE and AIR BRAKES with the knowledge I gained from this app but I still had to guess on several questions because they were not on this app. COMBINATIONS really needs attention, it had more questions that were not on the app like “how to tell if your trailer is skidding and which combination is more likely to roll over during a curve. I studied this app religiously and my failing was 100% due to questions not being on the test. I’m not sure if the test differ from state to state but I live in Florida if that helps the developers.
