a lot of profs prefer multiple choice over any other because its so easy to grade. I have a monumental task in front of me, 72 tests, each with 6 open answer questions. meaning I have to look at em all and dewcide if they are wrong. :-/ |

Oh, because over here they are very rare. I've had like 1 exam in my life that completely was a multiple-answer type.
Sure some exams have had a small multiple-answer part, but if you answered wrong on one question you got -1 points. |
