Happens Every Time
Yep, happens every time I get an MCQ exam. No matter much or how little I prepared, there's always some shooting required. But I'm not complaining. Give me MCQ over essay any time. I really do prefer shooting rather than trying to come up with a good argumentative essay that you would never know what grades it would turn up. At least with MCQs you can determine the chances of you getting correct or wrong for each question. And at least you have a chance of surviving.
In essay, when you don't know what the question is asking, you're as good as dead.
