Depends on the class.

I had a statistics course that allowed us one single sided page, but as long as your printer could handle infinitely small print, she didn’t care if you had magnification. You could hypothetically have keychain bible print for your entire book as a cheat sheet, it just wouldn’t help you in the allotted time.

My cheat sheet for R was nothing but codes because I’m not a coder at all (R and basic Linux are my entire coding experience, and it was fucking miserable) and that helped if I remembered to label the fucking codes. And LOL nope.

But I cheated in other classes by doing such nonsense as writing vocab on my shoes… in college language courses, which I paid for myself.. so dumb and counter productive.

I was never smart enough to cheat in regular school.. I just brute forced the work.. ironyyyyyyyyy
