We're about halfway into the semester, and I still haven't found an effective way to study for these tests. I just really need a study guide for each unit, because my teacher just leaves us in the dark, telling us to study.. So I don't have any clue what to do :(

If you have any tips/help please comment or send me a message , I would really like to get a good grade in this class, but me not knowing what to do or how to study isn't working out.

Thank you!
