i dont know if that is the same, but my prof. gave several LONG problems with a bunch of answers provided for each. You had to solve the problem, show ALL work, and have the answer you got match one of the provided ones. She looked at both, and gave partial credit. I mean, this kind of multiple choice DID NOT make the test any easier. Opposite, the incorrect answers that she gave were what you could have gotten if you made a "common" mistake. It sucks, imagine, you solve the problem, get the answer that matches one of the given ones, and it ends up to be a wrong one.
