I have varous review materials and notes that I have personally assembled. The one item which I have yet to prepare is a comprehensive formula sheet. I have begun compiling one but would rather not spend a full day devoted to assembling this with three weeks remaining and only a couple weeks left for studying. If you would be interested in making some kind of barter, let me know. I would be willing to pay $ for the sheet as well, we could discuss a possible payment based on the quality.
