Good content with some errors
I have a current STC manual for the 66 that I am studying. I have used these tests to check my knowledge and by and large the sample tests here are consistent with the STC content. However, there are misspellings and occasional wrong answer. But the ease of use and the ability to drill makes it worthwhile.

A lot of questions need to be updated as they are out of date, a few a flat our wrong, outside of that, the app is good and it is a great setup and easy to use, just need to update some questions as the laws have changed.
