Philosophy students: Turn up with the textbook along with all of their notes, and write a dissertation on why it all qualified as "one-sided."

"Shhh! Don't tell the students that letting them make a note card is actually tricking them into studying! SHHH!"

Cool professors just give you a formula sheet.

Honestly, if I saw that in class I wouldn’t care because it’s funny and helps with real world examples of some concepts

I remember buying jumbo note cards after my professor said we were allowed to bring a notecard without specifying the size.

I also remember commandeering my school’s ultra high resolution poster printer in order to print notes in extremely small font, alongside using LaTeX to let me format the document in a way that maximized my ability to stuff it full of information. The person who helped me do that let me know that the note sheet alone cost the school roughly $4.00/double sided page, or 1/100th the lab fee for the class I printed it for, even though that class had no lab and was in a regular, non-lab lecture hall.

In practice simply asking the professor if using a Möbius strip is acceptable will get them to amend the rules to allow double sided.

Möööbius sheet

I saw a meme about using red and blue ink and old 3D glasses with one red lens and one blue. That seemed pretty smart.

One time in high school, someone asked about this shape during a math exam and our professor showed us this shape. Nobody could do it, as the formula sheet was just a sticky note, but it wouldn't be a problem if someone could've made it, the professor said.

Bullshit. All these teachers give more instructions than this

it's Möbius stripin' time

should’ve specified that note cards need to be orientable. smh
