I think Specaircrew will be a UK/EU based instructor, rather than a student, as am I. The main feedback site is a discord server which you can access through the FB group given above. If there isn't a current discord invitation immediately available just ask, someone will post it. In general the new syllabus exams are now quite settled and the feedback is good. Provided you use the right question banks you can expect to have seen around two thirds of the questions in the real exam, or something close to them. Discord will indicate to you which banks are best. Having the correct training material is also important. I'm afraid I haven't seen CAE's most recent manuals but you wouldn't want to be using the 2016 edition of anyone's books for these exams.
