They ask you to pass a ridiculously easy test that even an ESL speaker could figure out, but then ask you to write an essay on a random topic in 30 minutes (which as a teacher I know is insufficient time to give someone unless they have seen the material upon which the topic is based), and then they decline your application based on "undisclosed reasons". Since I've been writing essays for at least 20 years (in several different languages), hold two university degrees in language-related fields and am an educator who teaches people how to write essays, I find that highly suspect. Clearly it is not the quality of the essay which determines if it is good enough but some other arbitrary criterion. Furthermore, you only have one chance to apply and if you get rejected you can't apply again.
