Okay, but it wasn't an exam, it was a quiz which isn't a big deal for my school (considering it's online) because we get practice quizzes at the beginning of lessons to see whether or not we actually need to complete the lesson. Not to mention I'm in credit recovery so I need to work through my classes as fast as possible and I can use all the help I can get considering we don't get help from our teachers or anything.
