Pmi

All this is ok. I want to put question to PMI here. Why don't they show score on the result. Just saying under proficiency, moderate proficiency and above proficiency doesn’t mean anything to failing student. I took exam recently and failed it. Some area shows proficiency some under etc. When I don’t know how many question I answered wrong, how I will improve. Before going to exam, I took dummy tests, and scored always more than 75%. In actual exam, I had numerical type of question, almost 20 question based on earn value, more than 10 on network diagram which I am sure I answered all correct. Now when I don’t know what was wrong what was right, how can I prepare for the future test? Can PMI answer this question? Please don’t give hypothetical answer, give practical answer. As of now I know all process and knowledge area on tip of tongue. Most inputs and outputs. Hard to believe, I couldn’t get through. Spent almost 6 months in preparing and 2 months rigorously. I had zeal for get through in first attempt. I know it is a tough exam, 81 % marks required to pass. I was sure with my preparation, I can achieve again.
