Just sorry you missed it, but, on the bright side: you are only 3 credits away from graduation, you can do this. Did you consider taking an online summer class at a local college?
If you haven't taken College Algebra, I can help you out. I am NOT a star in math, but my college taught a class on line (you never have to go to the college) that was so easy, I couldn't help but pass with an A.
I think they have a 4 week summer class starting next week or so that is very doable. Let me know if you are interested or need more info.
Hang in there, you are SOOOO CLOSE!
