Asvab idea??????????????????????????…

I put myself in a horrendous situation. i cheated threw high school.I received my high school diploma, I'm paying a huge price for it because i don't know crap about english and math. Do you think the GED class i signed up will help me on my asvab test? I have the asvab for dummies book, everytime i read the book it feels like im trying to learn chinese.
