Golf Ball(GB) is busy trying to keep her mind sharp for her senior year of high school. She's got a new machine called the Test-o-tron, which gives her 30 minutes of a test before it saves and stops for the day. This is a good way for her to stay smart while not getting sucked up in testing so she has time with others. GB: I'm finally done! Tennis Ball(TB): Great! GB: TB, what's happened while I was testing?
