Pros : Notes and Notes by Hammad book contains almost everything. Once you have completed it you are actually prepared for part 1 and part 2 as well. In current scenario when lots of diagnosis and treatment based questions are coming so frequently even in Part 1 this book has immense factor to play in this regard. Cons : super huge book. Very difficult to revise. For those people who are unable to study theory from any book I am suggesting to go through all theory of Passmedicine from its online version form along with questions. Don't use PDF version only as online form of Passmedicine contains more new question and they used to keep updating their theory according to current UK guidelines.
