问题如下：
After attending the CFA Level I exam, Chen discussed the exam's questions with other candidates that he felt confused about EPS analysis and then found the answer from the reading book when he went back home. He posted statement on the Facebook that, I make a mistake in the exam about EPS calculation and I hope I can pass the Level I. Chen most likely:
选项：
A.did not violate the Code and Standards by discussing the questions with other candidates.
B.did not violate the Code and Standards by posting statement on the Facebook.
C.violated the Code and Standards by posting the exam information on the Facebook.
解释：
C is correct.
After exam, Chen should not discuss any information about exam with other candidates, and Chen also should not post statement about EPS calculation on the Facebook. But “I hope I can pass the level I" is not a violation of the Code and Standards. Conducts of Members and Candidates in the CFA Program prohibits providing exam informations for the candidates or the public.
如果只是考试完之后，和考生讨论了，但是没有后面的发布行为，还违反standard吗？
