Actually, I think I have a learning disability in math - it became my nemesis in high school and college, because I was so utterly bewildered by the concepts (Algebra II/Trig, especially) that my brain just "glazed over" and refused to learn. My instructors were useless as well - insulting and patronizing me because I couldn't grasp the formulas and concepts. As a result, I basically bombed my advanced math classes (despite otherwise being a straight-A honors/AP student), which trashed my GPA for quite awhile. I struggled through chemistry and astronomy as well, because though I could learn all of the main "scientific" material quite easily, the math aspect completely and totally kicked my @ss. Humiliating.
