Dear Sir I am planning to sit for financial reporting exam on Dec 2018. But my Revision kit is valid up to June 2018. So is there any need to purchase the updated one due to exam format change or change in the syllabus?
You should be fine with the revision kit that you have. If you look at the syllabus for FR on the ACCA website then you will see that there have been no changes to the syllabus.
