I study in Lian Fang, Changchun, where all our classmates at Jida University study. Teacher Liu spoke very well, which benefited me a lot. It's really different from what the school teacher said. At that time, I also listened to Lian Fang recommended by my seniors. I went to Cisco official website to inquire about it and made a field trip. Feeling good, I signed up. Most students in our class took the exam at one time, but when I took the exam, I happened to have something to do at school. I didn't review well, so I took the exam again. The cost of retaking the exam was also borne by the school. My certificate just arrived in the mail yesterday, and I haven't gone to school to get it. Hehe, so happy. I like the Internet, and I will continue to study CCNP in the future.
