Judging by your poor scores, I would say college is not for you. Instead, I would recommend finding a way to get your high school diploma as soon as you can, maybe another school, GED, etc.
Then make you way into the fabulous world of Union Labor.
Here is a link to an official NYC document showing the prevailing rate of union wages for various types of workers. Many pay well into the 6 figure salaries to guys right now, after you make it out of the apprentice program, and thats not including awesome benefits. The Operating Engineers in particular just got a 35% raise over next 6 years after a one week strike, so the salaries continue to go up.
To get into many of the better paying Unions you have to know someone already in one. So if you do not, start banging the daughters of well respected members of the Steam Fitters, Electricians, Plumbers or Operating Engineers Unions toote suite. Toote suite that is french for.. well you won't need to know french, you are going to be a union man and proud of it. If your local city does not have strong unions, move to one that does! I recommend Chicago, LA, Atlanta etc. but not NYC, as we have enough a
Sswipes here already. Good Luck.
