If you're talking about the computer based training modules, you have to get 90% on all three reviews. There aren't really questions and answers, you have to be able to use an on screen DIAD (punching in and out, making deliveries/pickups etc.)
The training module could easily take you 4-5 hours if you've never used a DIAD before. As far as I know you can take the reviews over and over until you pass. Stop looking for shortcuts and just put in the time on the computer, this is something you need to know how to do.
