what is your advisce to me for the preparing in order to obtain the CAE
CAE is an exam that requires thorough preparation in the specific skills that are practised. It's not enough just to be a good user because many of the exercises are tricky in themselves, like the paragraph gap fills. The Reading paper requires reading at high speed in specific ways, so I would recommend exampractice,preferably with feedback from a teacher who has experience of the intricacies of a challenging exam. Once you get into the habit of testing yourself with their questions, youwill start to see the patterns and be aware of the tricks and traps they use. Are you studying alone or in an institution?
