I'm a junior in high school.
i don't go to a public school, not even private. I take an online school (you think it would be easier right?) I've already finished my math and chemistry or the entire year and i'm now working on english.
i've failed my math class, and i'm currently failing english as well. It's difficult since i don't have a teacher that's helping me, i have a text book and the books i have to read, and my parents are no help.
i have to repeat a year or am i just going to have to repeat the class?
