There have been some syllabus changes, from September 2020 and then from Sept 2021.
The precise changes at September 2020 are not on-line any more, there were some relatively minor additions relating to IT, but not too large I seem to recall.
Right at the end of the syllabus the changes are highlighted. Just look at Table 1, the additions and deletions and don’t worry about the rewordings.
By and large, taking care, you can use your June 2020 for March 2022. Are notes are up-do-date for all changes so you can address syllabus additions by looking there.
