I'm probably fishing in the wrong hole here, but thought I'd try it anyways. I have to start preparing for my 2ndary teaching certification exam in composite science. Does anyone on here happen to know of any really good comprehensive study materials? Needs to cover physics, astronomy, geology, chemistry, and biology. I'm pretty solid on biology, and have decent fundamentals in the other. But I sure could use some really good refreshers on all of them. Thanks!
