I have sit a number of test for United Nations in finance , and you do not get any feedback on your results or general results. There is no information about the number of candidates that sit the exam or how many made it upon the threshold, or what this threshold might be. So I think it does depend on the number of candidates and the overall quality of the answers.
This practice is rather strange compared to organisations like the European Commission, that publishes the number of candidates, and communicates individually the marks obtained and the threshold of the last candidate retained… which is by far more transparent. And helps a lot for subsequent selections.
