Bit of a random question. I bought my BPP books 2 weeks ago to begin studying for my PM Exam in Sept 19 only to realise when i opened them a few days ago to see that the study material has updated from 2018 to 2019. BPP have flat out refused to give me a refund on the 2018 materials i purchased as its over their 14 day returns policy… So i was wondering, shall i just use the books i have along with everything on here, or shall i suck up the cost and purchase the 2019 books. Will there be any major differences?
