According to the inquiry of official website of Ningbo Technician College, junior college students know that they graduated from junior high school but didn't go to senior high school. I went to a 3+3 technical school and graduated with a junior college diploma. The 3+3 academic system of Ningbo Technician College is an educational system, which is trained by stages in secondary vocational schools, that is, I study in secondary vocational and technical schools for three years, and then enter higher vocational schools for three years, a total of six years.
