Past papers

Unless you are looking at them as updated in an ACCA Approved current edition revision question bank/kit you would be well advised to not go further back than June 2013 (i.e. the extent to which they are available on ACCA's www https://www.accaglobal.com/gb/en/student/exam-support-resources/professional-exams-study-resources/p2/past-exam-papers/international-stream.html). Also, bearing in mind that these have NOT been updated by ACCA you should take great care with topics that he been subject to significant revisions in IFRS (in particular revenue, financial instruments and leases).
