I passed with a 53% on my second sitting (UK paper), my final paper, now an affiliate.
The secret is doing past exam questions (I did the last four years, all questions) plus read the technical articles on ACCA (very important). I did these with very little tuition as I am working for an NGO in a rural village in Liberia, so if you have tuition then its a plus for you.
In addition, during the exam day, stand in front of the mirror and say to yourself loudly………… I WILL PASS…..
