There's no such thing as "filtering" in academics. You don't get to kick out the students who didn't do well on the multiple choice and only proceed with the ones who scored highly.
I had classes in school that had multiple-choice quizzes every couple of weeks. It helped students figure out if they knew the material just covered and it helped the prof know how well he did teaching. They acted as checkpoints.
The mid-term and final exams were not multiple choice (at least not entirely).
WTF. OK, clearly you're contributing to the problem too. Yes, there is such a thing as passing and failing, regardless what your ideology has brainwashed you to believe.
