Today sucks!

I knew I did poorly on my math test, but I didn't expect to fail it or only receive 40%, I figured I would get 60%. At this point to pass the class I have to do extremely well on my next two math exams and the final, this is the hardest class I've taken. There is less than a month left and if I don't get my grade up, I can't graduate until the end of next fall quarter. The class is available in Spokane but I don't have the means to live there even for just 7 or 8 weeks. The class also build on a previous class that was also very hard and having three months off from math would be really bad if I had to retake it in the fall.
