The enrollment teacher is tired. Enrollment generally refers to all kinds of schools and training institutions to recruit new students. Generally, college enrollment is conducted from July to September every year. After passing the national unified high school examination, the school demarcated the admission score line according to the application situation of the year, and finally decided to admit new students. Enrollment classification: general college entrance examination enrollment, self-study examination enrollment, art and sports enrollment, adult college entrance examination enrollment, graduate enrollment, secondary vocational school enrollment, and non-academic enrollment. According to the different batches of college entrance examination, undergraduate courses are also divided into one, two and three, but they all belong to the same level, the same level (that is, undergraduate education level). At the same time, undergraduate courses are divided into "key undergraduate colleges" and "ordinary undergraduate colleges". "Key undergraduate colleges" and "ordinary undergraduate colleges" only focus on differences, and there is no essential difference. The former focuses on theoretical research, while the latter focuses on theoretical practical application. General higher education refers to the academic education that mainly recruits high school graduates for full-time study. It is one of the most authoritative measures of "China Higher Education Reserve and Cadre Training Plan" and the main measure of "China Higher Education High-level Talents Training Plan". The undergraduate education level (subordinate, provincial and municipal), undergraduate education system and nature (public and private) are different under the plan of higher education storage and cadre training in China. The difference of undergraduate tuition fees determined by the school-running system and the similarities and differences of graduation certificates among undergraduate (first, second and third) universities have nothing to do with the level of undergraduate institutions and the level of "academic diplomas". Therefore, the undergraduate degrees and diplomas of the first, second and third universities are the same, but the emphasis is different. Key undergraduate colleges (double-class construction colleges) focus on theoretical research, and ordinary undergraduate colleges. That is, key undergraduate courses focus on research, while ordinary undergraduate courses focus on application.
