Oh, this. My first few years at a university I was a horrible student. I'm talking C's, D's, lots of non-completes. I was a mess, academically. Then around 22, a switch clicked in my head and I made it happen. Dean's list, 3.8 average quarterly GPA, etc. I finished my last two years as a student trying to clean up the mess I made in my first three years.
In grad school, I was a 4.0 student. I got it.
I had the huge luck of being able to go to my local four-year, decent university for virtually free because my father was a campus architect. If it wasn't for the fact that I could squander my time taking random classes without fiscal penalty, I would have probably dropped-out or gone to a two-year school to get my act together. I only detail that to emphasize the mental shifts that sometimes happen with extremely-young adults.
I had a similar experience. I didn't really trash my GPA but saw the writing on the wall starting my third year. I dropped out, withdrawing in time to avoid a semester of bad grades. I worked, got an apartment, lived on my own, and at around age 23 decided I was ready to go back and finish. I often wonder if people would have more success at university if they took a couple of years after high school to go experience the real world and grow up a little.
