Does graduating in two terms look bad on a resume?

[ss20ts]

In all of my years of working, I've never needed to show my diploma or transcripts. These things just aren't required for the vast majority of jobs. Certifications I've had to show. Licenses I've had to show. That's just to prove I have them and they're valid. I have 2 degrees from UMPI. I completed my MBA in 8 months and it's a 2 year program. How did I do it in 8 months? I went to grad school full time and had permission from the Dean to take an additional course each term. I worked like a dog for those 8 months. I did school nonstop. No one has questioned how I did it. People are impressed that it was done in 8 months with a 4.0. People have commented on how great my work ethic is and how when I want something I go do it. No one cares that I rushed through a program. I did learn a great deal. I researched a great deal and wrote hundreds of pages every term. I have retained knowledge learned from my undergrad degrees at UMPI because I did the research and the writing. I did the reading as well. I also knew a great deal of it from my work experiences over the years.
