Changes to f7

Dear Mike,

Hope you can help me.

I have failed f7 twice now (in December 14 and June 15) and now I am having another attempt in September (hopefully 3rd time lucky).
I know I failed both time on ratio analysis question (stupidly thought it won’t come up again) so I will make sure I am prepared for it this time.

However what I wanted to ask are the changes to the syllabus.
Could you please let me know if there are any significant changes?
I only have old books and revision kit valid till August 15 and I really don’t wanna be cought out on something new.

Thank you
