Hi, i think you can use the 2011 version for the coming June exam, i have been using outdated books, i am now at the essential level. it’s also important to keep track on the examiner’s articles, sometimes, for some papers, you can find good summary there. I sat p7 in Dec., i didn’t even have a book, of course, i don’t know the results yet, i was just trying my luck. So old version is better than nothing. Try the old version + examiner’s article + opentuition notes + past exam papers + determination to pass = pass
