fetus,
First a question, how long did you spend at Mega State Unversity and how old were you when you left? (You are not required to answer this question on the board, but do think about it).
The younger you were when you left MSU, the shorter a time you spent there, especially if you stuck it out till the end of the semester, the better positioned you are to use some form of
"I thought I wanted to go to MSU. (They had a program in X, all my friends were going there, I wanted to go to the biggest and best school in my vicinity, other explanation which is true and appropriate).
Things didn’t work out (I was SOOO homesick, I did OK academically but hated needing binoculars to see my professors, The transition from high school to college was hard on me and I spent too much time drinking with my brand new frat buddies rather than studying, I took one class in Program X and decided I never wanted to have anything else to do with the subject, whatever is mostly true and doesn’t make you look too bad-- maybe even borrow Mouse Maven’s answer of dropped out for personal reasons).
I moved back home to regroup and promptly started attending Community College (while I figured out what I wanted to major in, while I got my finances figured out, while I demonstrated to my parents that I had learned from my mistakes, other explanation as appropriate).
Now that I have my act together, I want to attend Next School and major in X. I have researched my choices better, know more about myself than I did when I started MSU and anticipate graduating in Y semseters and hope to get a job doing Z".
Really, while many, many college students attend one school for 4-5 years and get a degree, students who attend a community college first and then transfer are quite common and get more or less the same education in the academic sense. Students who drop out after a semester or two at college are not unusual, and many of them spend time at a community college in circumstances not unlike yours. Having a degree will matter more than how many schools it took you to get it, and once you have your first job, no one will really look back much beyond that. And don’t forget Harriet the Spry’s advice. Emphasize what you went TO rather than what you left FROM whenever possible. No matter how bitter you are or deserve to be, future employers do not want to hear your greivances, especially in the interview process.
In other words, go for it.
