your first step should be to look at the support ACCA offers to self studying students and download the self study guide for papers P1 & P2
self study information
Also there are often events on ACCA learning community for Q&A on papers and other general events aimed at helping students who are self studying. I would check this every week and if there are any of interest sign up for it. They have the transcripts for other events had have already been held so you can still see if the event has passed.
There are also free exams tips with ACCA's approved learning providers BPP and Kaplan. To use these though you would need to give your details to register for them so it's up to you if you feel happy doing that or not.
