If you go to ACCA’s study support resources landing page https://www.accaglobal.com/sg/en/student/exam-support-resources.html and select the foundation level qualification and then FA1 Recording Financial Transactions – you will find an online specimen exam that you could use. If that seems too easy, and you would expect to be exempt from Financial Accounting (FA) in the ACCA qualification, you could select FAB instead.
