Ehhh
I used this app to cross reference with a couple other ones I used when studying for combination vehicles and air brake endorsement. The other ones I use are CDL prep and CDL Genie and those ones were word for word on the actual dmv written exam for the general knowledge portion. (Im taking air brake and combo this week so I’m brushing up) I did the free trial for this one and did two air brake tests and it’s garbage. Asks the same questions over and over again, theyre worded poorly and you’d be better off using literally anything else 😂
