I was able to (almost, 3 credits away and might just go to class 1 time) double-major with my bachelor's degree, 3 credits away from an Asian Studies certificate, and got my MBA in 36 months.
I CLEP/DSST a lot of courses as I'm very good at retaining short-term useless knowledge and taking multiple-choice tests, which got me through quite a few required credits. I was also approved to take 1.5x-2x courseload during my bachelor's because of my GPA. I finished it in (I think) 27 straight months.
Then, I entered a year-long MBA course and got my MBA.
I've considered getting a student loan (that I can discharge when complete) to get my PhD, just for the title, but I will likely never put it to practical use besides putting Dr. on my business card.
I also got about $80,000 in housing payments ($2250ish/mo) for going to school during that time. 🤑
The military has some good benefits. But, I also could've been sent home in a box instead. So, respect to those who didn't come home to get what they earned. 😢
