The CDL software was right on and help me prepare for my DMV CDL test which I was very nervous about taking. After receiving the practice test software and going over the three main test, I was able to pass the DMV test within four days with flying colors; I only missed 2 questions!
Now I can concentrate on the driving course and then later on the other endorsements.
I recommend TEST-CDL for those who are serious about getting their CDL permit.
