There are students at several AA programs who are only 20 or 21 years old. They most likely put forth a minimal amount of effort studying for the GRE, and even at their young ages, they were able to blow the math section out of the water. So if you're already almost 24 and you STILL can't score higher than the average highschool student, then you simply don't have what it takes to be an AA. I don't know why you can't get that through your thick skull. DO SOMETHING ELSE.
And stop whining about having to pay for another degree. You probably knew back when you signed up for your degree (I'm guessing biology) that your math abilities were lacking, and don't even try to tell us that we were the first people to point that out. But since you were stubborn and simply refused to recognize your own natural limits, you now have to pay for that mistake.
This time, choose something that actually accommodates your meager intellect. It also might benefit you to move out of your parents' house, get a real job (read: not a part-time, 3 hours a day joke of a job), and actually develop some sense of responsibility.
Maybe you'll have an easier time accepting reality if you take my advice and stop feeling sorry for how you were born. There are millions of others just like you who had no choice but to accept their blue-collar fates, and if they were able to do it without suffering a mental breakdown, then so can you.
Simply interjecting some truth here.
