I currently only have the BPP 2016/2017 notes for APM and was wondering if this will be ok to use for the Sep19 sitting. Has there been a lot of additions or retractions from the syllabus. I have looked online however it looks more like a shift around of where things are in the syllabus than being removed, but I wanted to make sure.
You should be ok. The main additions, as opposed to shuffling topics, relate to IT, eg blockchain technology. Our notes are up to date and should fill any gaps for you.
J19 kit should be fine, but look at the latest exams published by ACCA as these will not be in the kit.
