Not right this minute; take a make-up class or two for the maths you failed? One can always try again later if one wants; I went back to university at 51 and got my degree at 57 (while working full-time most of the time).

Do you have a college or university near you? Maybe you can get a job there; the bookstore needs helpers and they need people to work in the offices, etc. Take a keyboarding and computer software uses course and work for a bit, get a better idea of how things are and/or see if you can take some distance learning classes:
