Ratings and reviews

Ive seen too many wrong answers. Also i saw a few trick questions where multiple answers couldve been correct. I got the manual next to me to confirm my answers. This isnt going to work out.

I've found a few wrong answers in the lite version... maybe it varies from book to book, but I confirmed them with my cdl manual.

There are too many wrong answers which can really misguide students and new comers so they need to fix it since its not free. For 4.99 $ they can spend 5 minutes to check the answers before publishing it.
