MBA Aston University, early 1990's.
A brilliant experience for me, my then corporate employers decided to sponsor places on this MBA programme by distance learning offer this. I was part of the first intake of twelve people from different departments.
As I had recently broken up with a long time partner, I welcomed the new focus in my life and signed up without a second thought.
The best part for me was to have the group of colleagues to provide a really made support group. We would discuss each assignment, to understand the different viewpoints then each write up our own. This meant we all got better marks than we would have had individually without any whiff of plagiarism.
The time needed varied around assignments, on average I probably spent a day a week, usually two mornings at the weekend.
Being the first intake from that employer was useful too, as many of the 'corporate stories' were new to the lecturing team. In subsequent years, they were we discovered less impressed by the same examples 😀
This worked well for the nature of the MBA. It really changed my attitude from just understanding my own department's way of doing things to having a much better view across the whole business. My career took off too, helped by the confidence that comes from understanding business things much better too.
Is there a course you are particularly interest in? Can you see what you would gain from adding that to your CV or is it more of an interest thing?
As an extrovert, I'd encourage you to look to maximise the opportunities for interacting with others, online snd in person. If your learning style is different, that may be less relevant to you.
Good luck.
