Get off the internet and
get a tutor. Or use it to get some online tutorials.

When looking for a vocation or career, then start with what you like, have interests in, or have a skill that can be developed. What year are you in this "college"? What kind of math background do you have?
You really should be talking to your instructor, or the academic adviser at the school you are at, to at least find out WHY you flunked this exam, or get a much better approach to this class. If there is nothing left but accounting, then you should try vocational training, or get into a trade apprenticeship for a way to be gainfully employed later in life.
Obviously you are stuck in the terminology of accounting and your lousy study habits are just as obvious. You want easy, flip burgers, stock shelves or sell clothes. No degrees necessary and you will not have to live under a bridge, plus its HONEST (hard) work if not glamorous.
What kind of experience do you have from high school? I know, not what you asked, but like the others from the way you have framed your questions and responses you are definitely LOST!
