Would recommend using the free online tests they are way better. -- Trevinp502, 2023-11-28 ### ***** "Gets straight to the point" No fees good practice thank you -- richard44514152, 2023-09-20 ### **--- "Eh" The questions are good but I shouldn’t have to pay $16 just to *actually* try out the app. -- p0kèc4t, 2023-06-29 ### ***** "I think this app is trustworthy!" I need help with getting apps because they have a lock on it. I pray they will do the right thing because I have consumer rights and it is part of the purchase that has already been made in full for the product. The product agreement states that the App Store should be able to be accessed at any time. They are in breach of their service. We forgive them and we drop charges. Be without disputes! I will wait in patience. Now onto the review. I think this app is good because it provides study tools for free. The other apps that I used required membership even though they claimed to be free on the App Store which is a breach in contract because they claimed the price was free and they then attempted to charge money for their product. Be without disputes. I choose not to sue. We forgive them. They will make amends. -- Love161824, 2021-02-08 ### *---- "Not good" Was fine for first 10 minutes then kept crashing and not showing the answers I do not recommend -- Misterr01, 2021-02-04 ### ***** "Pre-trip inspection" It’s a very helpful -- grazyna gier, 2020-06-20 ### *---- "Not working" Can’t read anything but the questions and answers can’t read anything else showing up blank and black -- Daddy1129, 2020-02-13 ### *---- "Completely broken and a complete waste of money!" Was studying with original app when it broke. Had to delete and reinstall the new version, losing all my previously opened content. So I purchased the app and now none of the question show! It just shows the possible answers! Are we just supposed to guess what the question is? Fix this or give me my money back! -- Justanothered, 2019-11-24 [View all CDL Prep reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## CDL Prep In-App Purchases | Item | Price | |------|-------| | Unlock Everything | $15.99 | ## CDL Prep Discovered Keywords -
