If you attended school more than half-time for 4 years, you are no longer eligible, even if you did not get a degree. You could have claimed it in those years.
If you received degrees or credits equivalent to 4 years of college (a bachelors or 2 associates) then you are no longer eligible, even if you got the degree or credit from part-time study instead of 4 years of traditional full time schooling.
If you don't have 4 years of credit equivalents, and haven't attended more than half time in 4 prior years, you are eligible now.
