I think they don't even belong to Cambridge but just lie to get information.
Very good chance of this. "Borrowing" the names of well-regarded organizations, or even countries, is very, very common, and Cambridge seems to be especially frequently stolen. Or in this case, they might just be using those dreadful and boring Cambridge Business textbooks and have no further connection beyond that. Do the homework before you leap!
Received phone calls from this group saying they were from Cambridge Business in Beijing. Offered evening classes for Business students. When I called back to confirm the time and place they said the class is closed but would take my information. Real SCAM. sleeze and fraud. I think they don't even belong to Cambridge but just lie to get information. AVOID AT ALL COSTS!!
