For universities that give two tries for passing the PhD qualifying exams, are the two tries "equal"? In the sense that does the committee consider more carefully on the second and last try of the applicant before failing him/her?
Just an analogy: for driving tests, examiners are known to be more lenient on the second (and subsequent) attempt, and more strict on the first attempt. Not sure if it is true for PhD exams...
Just to ask any professors/students here who are more experienced in this matter.
