College credits should be completed 130 points. The total college credits are 170 to 180, including 45 credits for public courses, 50 to 75 credits for specialized courses, 35 to 60 credits for elective courses, 8 credits for graduation thesis or graduation design, and 2 credits for internship, so it takes at least 130 to get a diploma. Junior college is a basic part of higher education, and the enrollment period of senior high school graduates or those with equivalent education is mostly three years (the length of part-time junior college study depends on the situation). College education is mainly divided into full-time colleges and part-time colleges. Full-time colleges and universities are generally admitted by the national unified entrance examination for ordinary colleges and universities, and they study at school all day. Part-time colleges are usually adult education, online education, open education and higher education self-study exams.
