> Getting comfortable with these types of questions is very important.
It is important, but I think that a question is whether it should be important. That is, what is the value of a test that only, or even just primarily, evaluates how well you've prepared for it? One (or at least I) would like a test that somehow evaluated only actual knowledge / skill, so that one's score couldn't be improved by drilling. (As showerst (https://news.ycombinator.com/item?id=11067591) points out, the reason one wouldn't like drilling to improve the score is because it's the rich kids who are able to afford the time and resources to drill, and so you're testing the wrong thing entirely.)
