Disappointing results!

Studied with this app for my school bus CDL. Passed the chapters needed for the test with a 99% accuracy rate. I took the general knowledge test and failed because 10 of the 40 questions needed to pass I did not recognize. Don't waist your money!

Waist of time

The app is called “nj cdl”...just failed the test thanks to this app...literally this app has about 10% of the questions at the actual test.

Very good app! Totally recommend!

The general knowledge test it's everything you need to know about CDL, if you combine all the test together (will probably be 384 questions and will take all day) that's your test I took general knowledge test and I passed. It is not a wasted of money guarantee 👍
