The CCAT is basically a 50 question MCQ which is very similar to a run-of-the-mill IQ test. You need to be good in English and QUICK in basic mathematics to get through as well. 50 questions and you get 15 minutes to do them.
Spoken English test is pretty easy. You get several phrases where you listen to what they say, and you have to repeat back what you heard, exactly as you heard. It isn't hard at all. The second part consists of you talking about three topics they give, each you speak freely for about a minute.
