The rules for Class B are now in a document behind a paywall, originating from outside EASA from memory. The EASA examinars have been told that the rules they are working to are some years out of date but have not visibly reacted, nor has the syllabus been changed. When I get back to my desk I'll give you the document reference. Probably Pad Pilot are out of date, either accidentally or deliberately teaching out-of-date material to match the exam. Some sympathy there!
