| No, Math 54 isn't considered a weeder class. People have already been weeded before Math 54, in most cases, I think. That doesn't mean the class is easy or the grade curve is generous. You can search google and see old class sites for Math 54, check out the tests and the grading curves, in many cases...
Chem 1A is actually a huge weeder class for all the wannabe pre-meds. |
