Hey everyone, Its been quite awhile since I've posted on here, good to be back. So I have a really simple question; what topic should I begin to study in my free time when school starts? I don't plan on spending mass amounts of time on it as I have my other classes to worry about, but I do want something I can play around with. So far I've covered Alg II and everything below that, and this incoming year I will be taking Trig/Pre-Calc along with College Alg. I don't really mind what it is I study as long as it has to do with math/science. Oh, and, I'm taking Chem and Physics next year too. Thanks in advance!
