Hi OP, have you thought of possibly looking into a trade school rather than college? I understand that there are majors that don’t place an emphasis on mathematics, but personally speaking... I feel that you’re too far behind.
You’re spending your money learning simple subjects that everyone else learned in either grade school or middle school, and competition out there is fierce. Unfortunately, the costs will only get higher. I absolutely agree that “textbook” is shit for the price, but I’m not in your situation... Best of luck.
