According to my knowledge of online literature, this situation may be because the 2012 CIA exam was not checked online by the China Internal Review Association. As CIB exam results are generally regarded as confidential information, the Institute of Internal Examinations may not provide an online inquiry service to prevent the results from being leaked. However, you could also try contacting the customer service staff of the Internal Review Association to ask for more information about the 2012 CIA test results. They may provide information or help you contact the exam institution or the exam organizer for more information.
