Can sixth grade students take the exam twice if they are promoted to junior high school?

No. According to the official website of Xianyou County Chinese School, the school was established on August 22, 2018. It mainly recruits students from the first grade of primary school to the ninth grade of junior high school in the compulsory education period. Online unified registration is implemented for junior high school students. The registration period is from July 4 to July 6. The system is open from 9 am to 9 pm every day. If you miss the registration time, you will not be able to make up the registration. The first method of admission is random lottery and computer allocation, and the second method is to admit students with preferential education. Admitted students will announce their admission results on the school’s WeChat official account. Admitted students must pay fees and confirm their enrollment at the school, otherwise they will be deemed to have given up automatically.
