I went to Kelly Q and A as follows: Does Kelley require work experience? Answer: While we don’t require work experience, it is rare to be offered admission without it. We like to see students with at least two years of full-time, post-undergraduate work experience. On average, our MBA students have five years of full-time experience. Most students find their MBA experience far richer and their post-MBA career options far greater if they have a base of professional work experience to build on as they move through the program.
I would say : It is rare to be offered admission without it. Is this enough information to answer your question? I don’t know why Kelly school is contradicting themselves in 3+2 programs. Check and call them up; I am curious about it too.
