So here's my take on CDL Prep. I've tried a bunch of different study apps and this one's pretty solid. The question bank is extensive and the practice modes are helpful. I like that it tracks your progress too. The only real downside is the ads, but you can pay to remove them. Overall, it's one of the better CDL prep apps I've used. If you need to study for the written exams, this is a good option.

Description

Been using CDL Prep for a couple months now. It’s basically an app to help you prepare for the Commercial Drivers License exams. Pretty solid if you’re studying to get your CDL.

Here’s what you do: there’s a bunch of practice questions covering topics like General Commercial, Air Brakes, Hazmat, and more. And you can take a timed exam mode or just practice questions one by one. It’ll let you know if you got something wrong. There’s also performance tracking so you can see how you’re improving over time.

Look, if you’ve got a CDL exam coming up, you’ll probably find this app really helpful. It’s not perfect – the ads can be a bit annoying if you don’t pay – but overall it does the job. Worth checking out if you need to study for the CDL.
