Well, it will take me 3 and a half years to get a 2 year degree. So I'll be good for 5-6 years for a 4 year degree.
I've never failed a class, but somehow got stuck with several 0 credit courses my first year that I aced without doing much of anything, and withdrew from a couple more last year. I've never done more than 13 credits in a semester either, worried that any more than that would be too much to adequately handle. And all along I was led to believe I only needed one math class to get a 2 year degree, then last summer I was told I needed three because I didn't take it enough in HS.
I do alright, usually between 2.9-3.1, but it's taking me far too long.
