Look at the major. If liberal arts are not so necessary, it is a waste of time, but you must at least understand elementary mathematics; If it's science and engineering, and you really can't keep up with the progress of the course, make up for it. But generally speaking, adults should make up their own minds. University is a platform for stepping into society, so it is better to keep up with it. Otherwise, it is easy to rely on others after entering the society.
