When I arrived to the US' education system I was baffled at the amount of multiple-choice, scantron-based tests you have here. Everything becomes a choice between options. In a way, it's easier: you can appeal to pure luck, and you can appeal to your memory being "ignited" by the gaze at that one word who reminds you of the answer. I used to think this was inferior to an essay-type exam where you actually had to answer questions using reason and your memory, too.
But then I've gradually welcome the idea of multiple choice as more fair. In the end, when they thrown a lot of information at you and they want to know if you remember stuff, a multiple-choice 100% objective test is fairer than one where the professor judges your answers subjectively. A few professor can judge only how well argued your opinion is, but some will judge even your opinion itself.
Then I've concluded it should depend on the subject at hand. But some exact science teachers still prefer essay tests, and some social science teachers prefer multiple choice tests, which seems rather incoherent. Thoughts?
