In my engineering classes, almost all the tests were open book and open notes. The hardest classes only had two problems per exam and the teacher wrote those questions the day of the exam - so cheating wasn't really an option, which would explain the 30% pass rate in some of the classes... We also had to walk through six feet of snow, uphill, both ways.
