I have to say something about my personal experience. I went to junior college and went to Chunhua. People there desperately urged me to take the self-taught exam, saying how good it was to take the self-taught exam and how fast I could get the certificate. I also learned more things, saying that I would get my diploma in one and a half years, and the registration fee was basically not counted, so I gave the information to myself. It's all about memory and understanding, and no one taught me. It took me a year and a half to pass seven courses. In fact, I wasted three years like this, but I finally failed in the exam, three years. If I had been promoted to undergraduate course, I think my life track would be very different. Another student went to Shangyuan and said that he got his diploma two and a half years later, which can be found on Xue Xin. So, don't be greedy, don't think about taking shortcuts to improve his academic qualifications. At that time, he will regret it himself.
