I got 3 from Introduction to Databases!! I was sure I was doomed, even though I made all the SQL exercises (so got max points for that) but in the exam I was writing whatever breeze came out of my brain (apparently no farts).

By the way, if you go to the link I gave above and read the definition 1. I never write “dir” on Unix at the dept, but “ls” on MS-DOS at home. And then wonder what’s it complaining about.
