Especially when the questions are stupid:

What color are the crew life vest?
- Yellow
- Red
- High Visibility Orange
- Orange

The answer is, they're yellow in training when you play with them, technically high visibility orange for certification on the units we had at the time and "red" on the test (which was probably in the interest of manual simplification for the FA's to be honest). Legally; any color but yellow works.

The good news is, that dumb question cost me a perfect score and many are smarter than I.

You have to study diligently, but you are given the tools to succeed including a practice test which you can use as much as you want to gauge your preparation.
