Here are the details on the internal Ross transfer numbers (36.6% acceptance rate last year): https://michiganross.umich.edu/undergraduate/bba/um-transfer-brochure
You might consider a minor in business at Ross, if you can’t transfer in. It could be a good option to have. I don’t think Penn publishes internal Wharton transfer numbers, I’m not even sure if they open up any spots after freshman year, or if the only open spots would be from transfers out.
CMC and Penn are likely going to have very low acceptance rates in RD, but you will know soon enough. Good luck.
