Hunan University School of Chemistry and Chemical Engineering 1 class is not the best class. According to relevant data, Hunan Institute of Chemical Technology does not assign key classes and non-key classes. The university has already determined the major at the time of admission, and the placement needs to be based on the major. Therefore, the first class in the School of Chemical Engineering of Hunan University is not the best class, but an ordinary class assigned according to the major.
