A Hole in the Academic System?

Wanna hear a funny story? Chances are I have to take all of my calculus classes over again. Great news. Either my advisor was lying or they changed the rules. But anyways, Calc 3 requires a 'C' or better in Calc 2 to take it. That was the class I absolutely hated last year, the one I studied 8 hours straight before the final for. I got a D overall. But here's the kicker: Calc 2 required a 'C' or better in Calc 1 to advance. I got a C- in Calc 1. Why was I able to take Calc 2 in the first place then unless the rules changed? So therein lies the problem. I'm actually not allowed to take calc 2 over again because A.) I already took it, and B.) my requisite of 'C' or better in Calc 1 isn't satisfied. The rules of taking a class over again say that you need to have a C- or lower. So idk why they're bugging me about the 'already taken this course already' bullshit. Anyways, since my grade in Calc 1 isn't high enough to take Calc 2, I need to retake Calc 1 to retake Calc 2 to get into Calc 3. But when I emailed the head of the math department about it, she suggested that I take the course over the summer at either Madison or Milwaukee. Because she never brought it up, it's assumed that she isn't recommending me to take the courses over again here, most likely because I fell into a hole in the system, so to speak. If I can't retake courses, and I need Calc 3 to graduate, and Calc 3 requires taking courses over again, there's not much more I can do than to try taking it over the summer, or switching my major. I'm still in the process of working things out. If all goes as good as it can get from this point on, I'll be able to take either Calc 1 or 2 over again next semester. Life sucks sometimes :'[
