It was not necessary to practice the other papers for the three national papers because the difficulty and questions of the three national papers would be similar. However, if one of the questions in the national paper was relatively weak, it was recommended to practice other questions to enhance one's ability to cope. As for the local papers, the way they set the questions in different regions may be different. Therefore, practicing the local papers can better understand the characteristics and trends of the local exams. However, it was important to note that they should not only rely on the local papers but also the national papers to improve their overall level.
