If you look on the ACCA website for F6 UK Tax Exam Resources you will be able to access past papers BUT these have not been updated to FA 2015 so the answers are no longer correct! There is a March/June 2016 sample paper which shows a mix of the written questions in those 2 papers but remember it is now only Section C of the exam which is in the same format. You need to use an exam kit for FA 2015 from one of the approved providers but I would suggest from the questions you have been asking that you need to do a lot more studying and use fully the OT resources BEFORE you attempt past exam questions.
