I have been studying at Donghua University for five years. My feeling is that teaching is ok, and there are some better teachers. But because it is adult education, most students have no foundation. Everyone is very busy at work and has limited study time. Therefore, teaching is inevitably not very in-depth. University masters are all imported, and it takes more time to really learn well.
Speaking of exams, the adult college entrance examination is very easy. My friends around me have basically passed the exam. If you don't have basic sketch colors, you can go to Donghua for advanced art classes. It costs 800 yuan, and there are classes in culture class. Tuition 1000 yuan. However, personally, I think that the basic high school exam can be passed, and there is no need to take cultural classes.
