You already study IFRS in ACCA or CA and become well versed with it. These courses are designed for non-finanace managers or the finance managers who are too outdated with the latest development.
Go get classes if you want to learn IFRS.
Yap i agree with people who say that CA and ACCA people who r in practice are uptodate with IFRS but sometimes people in industry r out of touch with changes in ifrs.And this is where CIPIFR and DIPIFR by ACCA can help u recall your concept by learning and getting certifications.
Another important things is CPD points which r available to ACCA affiliates/members on passing acca approved courses like these.
