According to Baidu. Com, Gansu Normal University is a year or a learning cycle, but this is the actual operation. The learning task of the new school year starts from the current year 1 month 1 day, and the completion deadline is indeed the following year 1 month 3 1 day, which is very humanized.

Sometimes I can't learn it in Gansu Normal University, which may be a system problem. It doesn't matter. It's good to study again in a few days. Another reason is that you can't study too often, and the next article must be learned at least three minutes apart.
