1. Unqualified class hour assessment: after completing the class hour, you need to wait for the assessment of relevant departments. If the review fails, the system will show that you did not attend the training.
2. Insufficient class hours: Please check whether the completed class hours meet the requirements of the scheduled exam. If you don't have enough class hours, you will be prompted not to attend the training.
3. System delay: Sometimes, the system may be delayed, resulting in inaccurate display of class hours. You can wait a while and check the class time again.
4. Network problems: If you study online, network problems may also lead to inaccurate class display. Please check whether the network connection is normal.
