If you are taking it at Rio Salado then there will be no study guide. Your weekly lessons that you print out are your study guide. They are intended for you to follow along with while you read the chapter. Usually the teacher will post a message to the entire class at the beginning of each week with a summary of what you should be learning that week, with some links to helpful sites. That's it. I have taken 4 classes from Rio Salado because my schedule hasn't permitted classroom attendance up until now. I didn't love it, but it worked out well for me with my schedule. If you want a study guide you might have to look elsewhere for your BIO class.
