I have heard good things about WGU. I worked with a co-worker who went to WGU, and she highly recommends it.
I know the semesters are 6 month semesters... Could you get into a community college to take the 8 credits sow you can hold the license? I don't believe an MBA at WGU will give you more weight along your CPA... Especially if you plan on getting another accounting role.
I believe fall semester is 12 weeks? The community college route is a way to get the credits ASAP to get back to work... But it could be a nice change to take 6 months to just focus on learning interesting shit.
The MBA program is 34 credits (11 classes). Do you believe you could pass a class every 2 weeks? If so, props to you!
After thinking about it all... If I were you:
I'd register for WGU, and take 6 months off, and plan to pass ~50% of the courses for the MBA. Relax and study at a slower pace. Pick up some hobbies... Do cool shit! Come 6 months later, you'll pass at least the 8 credits, to then have a CPA... Then find a job that has a tuition reimbursement policy. Do another 6 months of WGU and have the 2020 tuition policy pay for that semester, and another semester that ends in 2021.
I think passing 34 credits in 6 months is a tad unrealistic.... At the very least it doesn't sound fun.
Good luck on your choices! I think the WGU MBA is a good idea.
