I've scheduled my PMP exam for July 17th. Does anyone know of any good quick reference guides? I'd love to have a small packet or something to refer to formulas, earned value, net present value, critical path, types of graphs/charts, or any other similar things that would be great to study some of those things instead of digging through the books or class documentation.

I've been taking practice questions and tests through PMP Study Hall and I am consistently getting about 70% right. So many questions that I get wrong seem to have multiple answers that could be correct. I've watched the mindset videos over and over and I haven't increased the number of questions I'm getting correct. For instance, this morning I had a question that was regarding stakeholders being upset about a deliverable. Two of the answers could have been correct to me. In this case, I was told to get to the root of the issue before acting. The two answers I was looking at were basically the following 1. Review the documented requirements 2. Call a meeting with stakeholders To me, I would want to re-review the requirements again before meeting with the stakeholders to see if we misunderstood the requirements and to ensure I was familiar with what we had discussed prior to meeting with the stakeholders to understand what is upsetting them. I chose answer 1 with this thought process. The answer was #2. I'm trying to understand why this would be the correct answer, since I thought you should analyze the issue before acting, and both seem like it would be part of the process of analyzing the issue, but I would have done #1 before meeting with the stakeholders. Thoughts on why I got this wrong? Edit to add: Here's the exact question from the PMP Study Hall practice exam. Multiple stakeholders express dissatisfaction with a project deliverable. What should the project manager do next? A. Review the final scope statement. B. Update the risk management plan. C. Review the documented project requirements. D. Schedule a meeting with the stakeholders.
