I almost failed my physics class in high school. I had an F in it for a while, but I managed to bring it up to a D. What's even more amazing is my Algebra II grade. I had an F in it most of the semester, and then I managed to bring it up to a C. Those are really the only two classes I was close to failing.
Well, either way, hopefully I can do better the next time I take the class. It's just the measurements have to be extremely precise, and we have to be extremely accurate in our calculations. That really threw me off.
