So we jumped straight from high school maths to Linear Algebra. Which leads me to wonder whether or not you were even taught multiplication in high school.
I almost dropped out of high school. The minimum requirements was rudimentary algebra. As in below MAT 096.
However, I have a friend who's graduating this year, a senior in high school, who's exactly where you were as far as math, suffice to say he has a perfect GPA, he also won the State Wrestling Tournament and placed 2nd or 3rd in a Nationally Ranked Tournament when not going ballistic on his education. He has scholarship offerings into so many universities.
I just decided not to go to school and instead to **** around. I'm not the best one for you to compare your education with.
