I hate closed book exams.
The problem with a closed book exam, is that you end up staring at terminology you’ve never heard before. And then you make guesses by literally interpreting the term. And then you start bullshitting with the hope that some of it—and sympathy on the part of the evaluator—might fetch you marks.
And while this is a pretty decent strategy for getting grades (although, none of my guesses today turned out to be correct), this doesn’t exactly leave a very nice impression about you.
And, you should care about the evaluator’s impression of you.
Especially, if the TA—the potential evaluator—is cute.
And yes, I spent half the exam time thinking of this post, and spent the other half trying to imagine how a B+ tree could or should work.
