Hi Jeff,
I hear you, and I am truly sorry you are going through this. Putting in months of hard work since January only to face a failing result is incredibly frustrating and painful. Your feelings are completely valid—you aren't just a "disgruntled student"; you are a professional who invested heavily in a goal, and it hurts when the outcome doesn't match the effort.
To address the disconnect you felt between the simulator and the live test, I want to share the exact design philosophy of the PM PrepCast creator, Cornelius Fichtner.
Cornelius has explicitly stated that the simulator questions are intentionally written to be highly detailed, complete, and scenario-rich so they can serve as an active teaching tool. They were designed this way precisely so you can thoroughly learn the underlying content through the questions themselves, and to prevent students from constantly complaining that the practice questions are too vague, incomplete, or tricky during their preparation. Moreover, Cornelius frequently warned in many PrepCast videos, that the questions on the actual PMP exam are notoriously vague.
Because the simulator is built for deep learning, it can create a major shock when you sit for the actual PMP exam and find that the questions are incredibly short, vague, and ambiguous. The real test is looking for a dynamic application of the PMI mindset under pressure, whereas the simulator is focused on comprehensive conceptual mastery to ensure you know your stuff inside and out.
Right now, please step away from the books and give yourself some time to process this. The effort you put in since January was absolutely not a waste—that core knowledge is still there. When you are ready to review your diagnostic score report, you can adjust your strategy to tackle the actual exam's format and cross that finish line.
Hang in there.
