The same thing is with education. (which is the most common meaning of test), multiple choice questions or very short answers are called tests, esseys and math problems are not tests, but "sprawdzian".

I didn't expect this:
Duo claimed I 'missed a space' in "When's the test?"
Must be one that LICA98 missed...
