I will definitely have a look at the Taxation by Melville, so you said you will advise to get the Exam Kit, I do have the Exam revision Kit for P6, can I use that for F6 paper? rather than buying one for F6?
I will have a look at the P1 paper and I might then do as you suggested, will 2-3 months study be enough for F6 + P1? With F6 I am confident about the basics as I just recently had a my final year university exam in Tax, and it was based on the BPP P6 Book.
