Why are they weeding out math and compsci students using calculus? The subject, as it's designed (at least in the US), has very little to do with what the students are expected to see, learn and pass as math/compsci majors. They are denying the students the taste of their chosen major by doing this bullshit. Personally, I am glad I discovered discrete math in time. Turns out, I love math, not the inane subject called "calculus". That's like weeding out English majors by having them pass a course called "folk singing and dancing" where you must passably sing and dance to not be weeded out. Stupid.
