Well for my Calculus homework, I have to graph only on graph paper. Should I just do everything on graph paper so I don't have to switch from graph to line and then back again? I'm having a hard time figuring out which way is best because the teacher will take off points for not graphing on graph paper! Btw. is it cheaper to print your own graph paper or buy it from stores? Does anyone know where they sell graph paper that has boxes on both sides? Thanks.
