Did Pearson Vue give more details about your score? It might be a system error (we hope so) or you have done something very wrong, like not following the instructions of packing your assignment files in a JAR containing only HTML and image files, not talking about your assignment on essay, or something that could led Oracle to summarily disqualify you.
We see that there is a glitch in the grading system. We are working on this and will resolve at the earliest. In the mean time we request you to kindly email us the assignment jar file, so that we can check and request our assessors to grade your assignment on priority and provide you the result status at the earliest. We completely understand your situation and sincerely apologize for all the delay.
Once you provide the assignment jar file, we will be able to provide you the result status in 2-3 working days time.
