Keep the class a W is still an attempt so it effects your grade the same as an F. You do not want to drop below full time if you are getting Financial aid. Go to your instructor and go often. Take both your tests in and ask for her to help you fill out the correct info. Ask her if there's a way to make up your test scores and before a test go to her office before the test to have her help you make a test outline. If she's not really thrilled about it she'll get use to it. If you really can't stand the teacher ask her to suggest a former student that past her class w/ a 3.5 or higher.
