On mainland China, most foundation programs are similar and as San Migs has described. What s*cks with the GAC is that it is owned by the American college entry exam institution called the ACT which siphons off money and which cares little about who enters the higher education abroad and in its own country, the US. Needless to go on debating the scarry opportunities the program provides the foreign facilitators with.
Cheers and beers to all the pro foreign facilitators with elephant skin :)
