I think the CPL alone is 9 exams.
I am just working through the 7 IR exams and have never seen so much bull***t in my life. The relevance to flying is much less than 5%, where the material was once relevant it is obsolete by at least a decade, and the questions are often ambiguously phrased (poor use of English). A lot of the answers are simply wrong, or so highly type- or context-dependent they are meaningless. I don't understand how, 10+ years after JAA came in, this appalling situation has been allowed to continue.
So I don't envy anybody doing the CPL exams.
