Haha, they would have died. ;) I vaguely remember my digital electronics exam. You had to design some kind of memory I think, by hand, drawing all the gates and stuff. Good times!

I do this in another course. 45 questions in 60 minutes. If you need to google stuff, you won't have time to finish the exam.
