i don't know what u mean" not good enough". they aer in canada, not in china. there are many external, internal, objective and subjective factors to determine whether they can be there. every bodies also have themselves consideration, after all going aboard is not a easy thing for chinese. based on my information, among the last year yes canada students,some graduated from domestic famous universities and have found a good job, after they finished the yes canada program last year.can u say they are not good enough, because they didn't take the stupid GMAT? at least for me, i don't think so!
i do think that every people should look at any problems with an active perspective, wherever we are in china or other counties.
give an advice : talk to yes canada students see whether they are good enough.
