Those tests that companies use to weed out job candidates are so ridiculous. All those tests prove is whether or not a person is good at passing tests.

Before you throw in the income-towel, if you have a college degree you have options during the school year to make an income, and avoid the ramen-noodle, food-pantry route. You can substitute teach. I don't know where you live, but every city has substitute teaching companies that place substitute teachers in schools. You may want to give that a shot until you can find full time work. Of course, if you hate kids, then it will be a challenge. But, if you don't mind spending 7 to 8 hours a day in different classrooms, following a teacher's lesson plan, making sure the kids do the work their teacher left for them, and collecting a paycheck at the same time, then you may want to join some temp agencies.
