not even the internet can help you
I hate making crib sheets. Just give us a goddamn formula sheet if we need one! Crib sheets take time away from useful review (such as solving sample problems and thinking back on concepts) and give horrible hand cramps. Your crib sheet is only a testament to how small you can write and NOTHING ELSE.
One thing I love is when professors allow a test to be totally open-note. This means that you actually learned something in their class that can't just be looked up easily online. But it also means the test isn't just going to be regurgitating formulas -- oh no. It's gonna actually involve your thinking brain. Those are good tests, those are good classes.
(fun fact...the professor for my class that has an open-note final actually has a beard like that)
