Hi there. It all depends on your personal circumstances and whether you have enough time to dedicate to revision. It might help to produce a study plan working back from the exam date, as this will give you a better idea of what you achieve in that time. Here is a link to ACCA's study planner template.
If you're new to ACCA, we'd really recommend checking out the study support resources on our website. You have access to technical articles, examiner reports, tips for effective revision and more.

Hope that helps and best of luck with your studies!
