Math. No, really. I went to tutoring for math from grade 6 to grade 11. My tutor told my parents that I had a learning disability in math LOL.
I didn't need it senior year because I didn't have to take math. We had these yearly statewide tests called the FCAT, and the years to had to pass were grade 4 (to go to middle school), grade 8 (to go to high school), and grade 10 (to graduate). Guess what? Those were the only years I've ever passed in my life. From third grade to senior year.
Thankfully, I only had to take one math class for my major in college. I passed with a C.
