If you go to the ACCA Study Support Resources portal https://www.accaglobal.com/lk/en/student/exam-support-resources.html you will find a list of all the exams – it is not “just accounting”. If you then select an exam, you will find a list of resources including the syllabus for each exam. The syllabus provides a detailed study guide of all the topics for each exam.
You will find “finance” topics mostly in Financial Management and Advanced Financial Management.
