test tomorrow!

I started freaking out when I heard Science, Technology, and Society tests were hard. What's worse is we have a test tomorrow and I don't know anything!! I talked with several people who are taking the class, or have taken it already, and I'm getting pretty much the same feedback- it doesn't matter how bad you bomb the test. Appearently, as long as I pay attention, come to class, and contribute to discussions I'll pass with atleast a C+.
