Creating an exam is an art. Or is it scince? I would go for art.
I am trying to create questions that can measure student's understanding. The questions are "simple", in a sense that if you know it you will be able to answer it quickly (of course) but it would take forever to guess it. But, this is the kind of "know/don't know" question. Black and white. Especially if it is done through multiple choice-type question. It's easy to mark, but it doesn't have the granularity that I need.
I guess, essay questions are still needed. Okay, I'll throw in 4 essay questions.
Good luck in your exam tomorrow ...
