My current organizational method is keeping a binder with a folder for each of my classes in it. I keep only the work, notes etc. for that one class in its designated folder. Also, each day  I write a list of assignments and things I must complete that day on a sticky note. I check things off as I complete them. My method works because I am used to it and it helps me remember important things like going to talk to the counselor, signing up for the SAT and ACT, and what homework I have that day.
