Depends on how you look at this course. Although computer professional courses in major universities are relatively backward now, these basic courses are the foundation of computer specialty, so we should firmly grasp them anyway. Maybe you didn't feel much use when you were at school, but in actual development, whether you can master solid basic knowledge often determines the upper limit of a development engineer, which is why many large Internet companies focus on some basic knowledge inspection, whether it is school recruitment or social recruitment. After all, what you can use can only determine your lower limit, while your basic knowledge and learning ability determine your upper limit.
