Thinking of moving out

Let me know your experience of working full time job and being a full time student. Did anyone live alone in their apartment and work while studying. Did you have a car and everything to support yourself?? I am really thinking of doing this but I don't want anything distracting me or making my graduation date delayed. I'm a college student. 21. Never had a real job except online. And the most important question is how long did it take you to graduate? Did it take you the regular 4 years?
