The online HKCEE score is accurate. HKCEE score book only shows results, such as excellent and passing. Some students usually get different grades. Maybe that man cheated in the exam. In some areas, HKCEE's invigilation is very loose. For example, here, we can just look through reference books and take mobile phones. Therefore, the HKCEE score displayed online is true, but it may be false during the exam. Perhaps some local educational institutions are also aware of this, so let the query results be for reference only, subject to the notification of the results.
