Thanks for the idea, Sufyan! Of course, I should have checked the syllabus for these two periods. I’m going to take the global F4 and the new syllabus says it is effective for September 2015 (for CBE exams from 23 September 2015) to August 2016. So it seems in my case (my exam date is Sep,19th) I can use the June 2015 revision kit. And yes, these two syllabi for F4 GLO seem identical)
