CS3 had a high failure rate?? Do you have a ballpark sense of what it was? I could understand it if 61A had a high failure rate, but I thought CS3 was the way to weed yourself out of CS without taking a hit to your GPA (i.e., realizing that you weren't able to do CS while still being able to do decently in the course, instead of taking 61A and having it be so hard that you failed).
