Repeating this phrase " MBA only started in 2015" makes me rest my case. My Cousin started in 2013 and graduated in 2015. Where are you getting this from?

Doing MBA while working doesn't make that program easy, most of them were domestic students progressing their career, and were in good number. I would respectfully take a note from someone who attended and relying on web search. I guess eligibility says " Experience is an Asset" on unb website but that doesn't make the whole class with non-experience students. there are basic requirements listed and selection process is depending on number of factors, class limit is one of them.
