P3 BPP books June 2016 ok for December

Hi I bought BPP books for the March and June 2016 sitting but did not do P3, as wanted to concentrate on P2 as it was huge. I will be doing P3 in December 2016, are the books ok do you think or is there a lot of change and I need to buy new updated books. I do watch and use your study lectures as my only 'taught' study - I just use the practice and revision kit and the study book for any extra reading should i need it ? Thank you
