Hi Jacob,
I am sorry to hear that you failed your PMP exam twice, but I like how you are not giving up and still reaching out for help. Like most people mentioned it here, using PMBOK alone will not be sufficient to pass your PMP exam. I will recommend using other PMP study resources and materials such Agile Practice guide, PMBOK 7th Edition, PMI chapter, PMP exam prep simulator, PMP APP (i.e.: PMI PMP Exam Prep and PMP Handbook, these are free apps), and I also recently learned that PMI now offered PMP Exam prep simulator for $99 USD. I will recommend giving yourself enough time to study before you register for your next and final PMP exam. You have already taken the exam before, so you already know what to expect. And with a very detailed study plan, you would be ready to pass your PMP. Best of luck!
