Darden's sister school, the AACSB-accredited school of commerce at the University of Virginia, runs a cute mini-MBA programme. The MBI is a certificate program run either online or in a summer school on UVA's beautiful campus. You can read about it at: www.commerce.virginia.edu/mbi/ The on-campus program includes an additional element on communication skills. Both versions cover accounting, finance, marketing, management and Excel training. Aimed at both senior undergraduates and at working professionals, this looks like a great way to get some MBA basics under your belt.
