Query on questions

Sir if we take 4 papers of Acca per year i.e 1 paper of Acca every 3 months, then if we do not get so much time to do all the examples of P5 which are provided in OT notes and all questions of the Exam Kit, and we have to choose any 1 option between the below 2 options then which 1 is a better option in order to Pass P5?

1) To do full Exam Kit (Kaplan) for all sections BUT no example of OT notes

2) To do all examples of OT notes and only those questions of Exam kit (kaplan) which are past Acca exam questions.
