I couldn't resist this, could I?

Your English Skills:

Grammar: 100%

Spelling: 100%

Vocabulary: 100%

Punctuation: 80%

Does Your English Cut the Mustard?

And the 80 was only because I reckoned both answers were OK for #6, so picked the one I was fairly sure was the "wrong" one.

Hells' teeth, I'd never have admitted it to anyone if I'd done any worse on a test set by Americans! (Or maybe Canadians - people who talk about "flavors", anyway.)
