Different schools, different majors and different grades have different curriculum arrangements, which has nothing to do with junior college and undergraduate course.
Powerful colleges may be more inclined to find jobs in the future than some undergraduate schools, and learning and teaching are close to actual combat. But undergraduate schools generally have better learning resources, such as libraries. There are very few things that teachers can teach in universities, so the library is relatively important, and of course there are network resources, which is fair.
