Make sure you actually meet the requirements for rank, including both exam score and experience points, and that these are actually on your online judge record. If you’ve checked both of these and still believe your rank is incorrect, contact the IT director to review your record. If you just earned points at a competition or other event, wait for the points to show up on your online record. A promotion check is run against all participants in reported events, so please wait for the web records to be updated (approx. monthly).
