If I started college in Fall 2012 and graduate in Summer 2016, will I have graduated on time?

I take it you are the same person with a new username obsessing about the time it takes one to graduate.

Or, maybe not. Maybe there are two of you.

Are you sure you are a college student? I'm not sure based on this question unless you have a liberal arts degree. Do you have a liberal arts degree?

Based on other threads, this person is an attention troll who is bored or has mental health issues, or both.

Okay, doen, you're better than average. 59% graduated in six years. It took me longer than four years, because I had to work. My wife let me attend college full time in my senior year. Having majored in Accounting, my career was more than satisfying; it exceeded my wildest expectations. I worked in management positions for over 80% of my working career.
It's been my observation that it doesn't matter where one graduates from; it's how productive you are.
