Cheat Sheet or Not?

[JoeH]

Depending on what was being tested, I have had math tests that allowed taking in a sheet of formulas all the way back to high school. Also allowed in some college classes. High school was over 35 years ago, so it is nothing new. In fact, I sometimes preferred the non-"open book" exams, the instructors tended to not go quite as deep into the proper application of the information taught in the class from the book on those.
