Im failing high school and i want to fix it. i just dont know what to do, i dont do the homework and i couldn't care less about the curriculum. i have tried everything to motivate me. . i dont understand my math class which is probably why i am failing it.

You evidently don't want to fail. You don't have to care about what you're learning, you just have to care about succeeding enough to attempt to learn. Do your homework. If you do the homework, stay after school for tutoring, you'll learn better for when the tests come around. Also try to think about your future and how important it is to you to get through high school.
