Applying my skills

This app has helped me pass all of the written parts of the CMV parts,but of course I read all the chapters in the CMV booklet that I received from my local bmv office. So with reading the chapters first and understanding why each individual answer is correct when answering the questions. So with having small children in school and having a full time job while studying,this app is very awesome to have to be able to study while constantly on the go. A big huge sincere thank you to the creators of this app for helping me and family live better lives.

Great study guide highly recommend!!!

I recently took and passed my class A CDL permit test by only using this app. I aced all 3 sections which were general knowledge, air brakes, and combination. The app has a great study system that allows you to see exactly which answers you get wrong and forces you to answer the wrong questions 1-2 times before it allows you to advance to next section. I was a little skeptical about the app but I crossed referenced some questions to answers from the book and they were right on. Great app!!!!

Great app

Simple to use love the way it repeats the same question til you get it right. I feel that is one of the best ways to study.
