Look for a study partner a serious one, for u not to b lazy, and do as many practice question as possible under exam condition, ,
Hope you are doing well. I recently gave my f1 paper and scored well , this paper is all about how much you understand the stuff!
I can suggest you the following sources, which can help you, as you are doing self study:
I have attempted F1 recently on the basis of self study. So as per my experience just read kaplan book throughly ,understand each and every concept and then solve bpp kit, opentution and ACCA mock. That would help to faĺl the victory in your basket.
Good Morning - I passed F1 a few years ago, but as well as the other comments, go through the revision kit book twice at least and do as many questions as possible from the Open Tuition site, as well as the ACCA own mock exams etc.
Remember that it is multi-choice...so anything can turn up in the exam.
Hope that helps.
