Don't apply for Zhejiang University Distance Education. He was very strict in the final exam and didn't give an answer before it. If you sign up, just wait to hang up. Only 60% can get a diploma, and the rest die over and over again. I recommend this one from Zhengzhou University, which is relatively simple. Basically, you can get a diploma by applying for the exam. I just applied for the second year of Zhejiang University, and now I am ready to drop out. I study electrical engineering automation, and I really can't stand it.
