Where can I get ACCA F3 very tough PRACTISE questions with level of difficulty very high? This is so in order to check if I can work out these questions or not.
As we say throughout this website (and in the free Lecture Notes as well, on the second page) you MUST buy a Revision Kit from one of the ACCA approved publishers. They contain lots of exam standard questions and practice is vital. Whether you find the difficulty very high or not is irrelevant – what it is important is to practice questions that are of exam standard.
