In college I took a database class, it was pretty basic overall as I had been playing with MySQL for a few years at that point. On the final exam I got a 90/100. The test was 10 questions that just had you write SQL to answer the question. I got all the queries 100% correct... except... I didn't put a ";" after each query. On a written test. I'm still a little bitter about that.

I had a course on natural language processing with Prolog, and the first third of the exam was just evaluating Prolog expressions and figuring out what syntax errors had been made. This of course took so long that everyone spent at least two thirds of the time on that one portion...

It was a weird course, though. Because we spent so long learning Prolog, the second half of the course was really rushed - lots of learning about English grammar and syntax trees, and how you could model them in different ways, and then the last lecture was just "oh, by the way, here are all the ways this doesn't work and is a complete dead end - your exam is on the 14th".

IIRC there was a part two to the course, but I think it clashed with something I was more interested in so I never took it. It was cool to learn Prolog, but I wish it had been a whole course on just Prolog and actual present-day use-cases, as opposed to this weird half-and-half course about an approach to NLP that even back then wasn't being pursued with much enthusiasm.
