2011 was the first active year of the new syllabus. Questions pertaining to all the topics are to some extent relevant - however, some of them are not (you'll probably know when you encounter questions and are like 'lolwat'). The 2011 paper was kind of a transitional year imo - it had some older style questions. Nevertheless, finance questions from pre 2011 are generally really good
(I've done them all lol).
The old syllabus also had a separate global topic (not integrated into each topic). Look out for different names of stuff.
