I used to work at EF, and had coworkers there that had worked at Wall Street before. I thought EF's educational standards were a little on the low side, but my coworkers who had worked at Wall Street actually said Wall Street's were worse and they like EF better. All I know for sure is that EF's main focus is building its image through chic-looking centers and slick advertising campaigns. Little thought goes into academics, maybe because the people running the company are businessmen, not teachers. Just my two-cents worth.
