If it's the same as a "Foundation Program" (a one-year preparation to send the kiddies to a uni in the UK, and maybe other locations) expect a general cluster flux. To the extent that you are able to organize anything, that may be how organized it is. Several years ago I was handed a work assignment to teach one of those courses. My class was supposed to be about the IELTS exam, I found out in about week 12(!) There was one other foreign teacher who was light on grammar and pronunciation but at least had some English-only excursions to run errands, etc. I'm not sure what the Chinese teachers taught. In the end, it didn't really matter as the UK school was happy to provide remedial English as an expensive prerequisite for low IELTS achievers, at a higher tuition fee, of course. By now, that Chinese uni presumably has a better handle on the program, but maybe not. The good part was the class was small, and of the four students, one of the girls could understand English (and didn't need the remedial classes- or very little).
In fairness, that was my only experience with the one year program. I've also taught in the "International Programs" where the students are in China for the first three years and then finish the degree in either the UK or Australia. That's probably a more reasonable program, except for the "first three years in China" part. I'd say in the International Program I've had some students who would do fine in my English major classes, but there are more at the lower end of the spectrum. Better last year than previously, though, so perhaps my uni is screening out better. (Both programs are at much higher tuition fees and open to students with low gao-kao or no gao-kao scores.)
