100% pass the CDL Tests

This app is amazing! It’s word for word just like the DMV will ask you. One thing that would make this app perfect would be to add class C questions and answers since you have to re take your class C also, but other then that this app is a blessing.

Worked for me

Had the questions I missed on the actual exam due to different wording!

Fantastic

This app is fantastic! I read my state’s CDL book and practiced on this app for about a week. I passed my General Knowledge, Air brakes, combinations and tanker in about 25 minutes. There was one or two questions on General Knowledge that weren’t in this app but other than that the app was dead on accurate!
