Watch (again if you have already watched them) my free lectures. They are a complete free course for Paper FM.
Attempt every question in your Revision Kit (without looking at the answer until after having attempted the question). If you have not got a Revision Kit from one of the ACCA Approved Publishers then it is essential that you buy one.
Work through all of the Paper FM technical articles on the ACCA website.
If you have any problems with any of the above then ask in this forum and I will try to help 🙂
