Here is a photocopy of my certificate as an example.
The exam is divided into 4 categories, Verbal, Analytical, Numerical and General Information.
I was quite sure I failed the exam because of the verbal usage part, I got 83.72%, which is quite shocking for me at first (since I did not know the score system then) because I'm sure I only got less than 50% correct of the verbal usage exam. It was that difficult! But because the system ranked my score highest to lowest, I got the 83.72% score. I was pretty confident with the analytic and numerical exams though (since this is my thing), I got very good scores while I was practicing on the reviewers. If you noticed I failed in general info, the questions was about laws and constitution and I sucked at it. I barely survived my Political Science and History in college. hehe.
I know this fact and I'm sure about it because it is the same with PRC board exams. They use the same system in Electrical Engineering Board exam, they use the quota system.
