As a first year high school testing coordinator, at a fairly large school, I knew nothing about AP. A fellow coordinator had used Total Registration and encouraged me to do the same. I loved the ease of it and the reports I could run to help me with ordering, with free/reduced lunch waivers, counts, and communication with those registered. The kids could register at their convenience and parents could pay online. I hate to think of the record keeping I would have to do had I not used TR. It was a life saver.
