From all the papers I saw, there was nothing that I couldn't do, whether it was off the syllabus or not I don't know. As for teachers knowing some things won't come up, I take it you're referring to the recent news of the examiners telling teachers at conferences if those teachers paid £x,000. I highly doubt any of these teachers were from government funded schools, seeing as they barely have money to replace a broken bin. There are still things "not on the syllabus" being put on exams now-a-days, over the last two years it has been in the news twice. With the introduction of the A* (in A-Level) exam boards started putting on "stretch and challenge" questions which are totally off the syllabus, which is targeted for those wanting to get an A*.
