Test yourself: AP style, spelling

Here are some well-designed interactive tests, if you're prepping for a job interview or just want to brush up (I take the AP style one occasionally to stay sharp).

This spelling test has a practical level of difficulty. (Many copy editor candidates will face a spelling quiz on part of a paper's copy editing test, and some reporters will too.)

Great interactive quiz on AP style here, with clear explanations.

In fact, there is a battery of great tests at Newsroom 101 -- even specific grammar problems are addressed.
