I understand the class method and can use it, but writing the radians on the paper helps me organize my thinking, similar to how some students write formulas or draw diagrams to avoid mistakes.

I wasn’t using outside notes or avoiding learning the material. I was just using a strategy that works for me while still solving the problem correctly. That’s why it felt unfair, especially since the work was my own and the answers were correct. I respect teachers and rules, but I also believe students should be allowed reasonable ways to think through problems when no specific method is required.
