I had a quiz today in physics and it was open note, so for once I actually took notes yesterday. Turns out I took notes on the wrong section, so I didn't know any of the information on the quiz. The other problem is that I have a textbook, not an ebook, so it wasn't like I could just whip out the book and read through the section. (Also the textbook is at home, because I'm not lugging around a textbook like a middle schooler.) But then I remembered my mom bought a physics help kindle book that I could access, so I read through that and found the equation I needed to use.
