Share 'Are the "practice exam" questions anything like the "real" exam?'

Hi all! I've been preparing for the CAE exam (this Friday) and in the process have taken numerous "practice" exams. I'm not studying from them but I have been able to identify weak areas that I needed to address. That said, are the questions on the "real" exam similar to those we've been seeing on all these practice exams? Thanks, Gwen Biasi
