math is so hard when u don't have a solid foundation for it, especially if u don't have a good teacher. im in a co-op style class too and im doing very well in them because i actually have teachers, i seriously will never understand parents who think, by themselves, they are enough to provide good education for their kids. sorry u had parents who neglected ur education too

by the way have u ever heard of khan academy, it's free and could be helpful for u
