<p>@aRandomHobo: Calculus is a tricky course to classify; a professor can make it very simple, a class where taking derivatives and integrals is pretty much it, with one or two very straightforward “applications”. Other professors can make you understand it very in depth; and as a person who is very passionate about math, I can tell you the depth to Calculus knows no (greatest lower) bounds. Usually, people in high school can manages A’s in Calc without even understanding the most fundamental stuff, like the definition of a derivative. </p>
<p>There are numerous ways to fail a class, and for numerous reasons. Get off your high horse and realize that almost every situation is unique, and making arbitrary comparisons doesn’t help anybody, especially not this person who is probably just freaking about getting their admission rescinded for ambiguity in grading (something that shouldn’t be a problem in math and science courses, and many times when it is, bad things happen).</p>
