I'm not an expert in IQ or testing, but wanted to encourage you to not give up on yourself. You write more coherently than many people I see on the internet and I suspect you are more than capable of success in college. If your grades or other circumstances are such that you would find attending a four year university difficult, community college is always an option, either full or part-time. Taking the basics may help you decide on a career. Try not to worry about IQ, or the past, which is something you have little control over.
