I was admitted to Anqing 9 16 Qingbei class, but I have been in that class in the later period.

Of course. According to official website of Anqing 9 16 school, the Qingbei class redistributed after the division of Qingbei class in Anqing 9 16 school can stay in that class all the time and will not be separated because of the decline in grades. Anqing 9 16 School is a full-time private school invested heavily by Hefei Dianyi Media. The school is located in the government and cultural center of Da Qiao Economic Development Zone, Anqing City.
