Our lectures and notes are for the September 2018 exam (if you look at the front page of the notes then the relevant dates are shown!!).
You can use your Kaplan textbook OK, although if you are watching my free lectures then you do not really need the textbook – the lectures are a complete free course and cover everything needed to be able to pass the exam well.
What is vital is that you have a Revision Kit – they contain lots of past exam (and other exam-standard) questions for practice, and practice is vital to passing the exam.
