"All the questions in the chalk APP will automatically record the questions you have done. The official does not support emptying the questions that have been done. Even if the questions in the chalk are emptied and re-selected, the records of the questions will not be deleted, and the records of the questions will always be kept in the account. However, the civil servant exam questions in chalk are similar, and those from other provinces can also be written. If you really want to retake the exam, you still have to use a new account. "
