Frederick County Calls Again

I now have a new, unpaid position with the school system from back home. Apparently, the person who wrote the math questions for the academic tournament is no longer doing so and my name was mentioned as a replacement. I guess the debt I incurred having the access to the administration of my high school due to my mom working there is being called due. Thus, for the next month or so, I will be coming up with 15 mathematics questions each week covering precalculus, statistics and probability, trigonometry, calculus, and other high school math subjects. On that note, does anyone have any high school math books sitting around? My math books tend to be at the undergraduate and graduate levels.
