Rennes I is good, and the characteristic economics is very strong, but Rennes I is not so good, and there are no three certifications, which is just so-so in France. French high-level businessmen must read the top ten, all of which are accredited by EQUIS, AACSB and AMBA. If you don't have this certification, don't read it. Gold content is not high.
HEC, EDHEC, ESSEC, Lyon, Grenoble, Rouen, Reims and other higher business schools are recommended, and the business schools have passed three certifications.
