Schools should teach students about basic information specific to let them know the information they are interested in, each person has different interests. Teach the subjects they want instead of forcing them to take all of the class with the subject is unnecessary. In my opinion it's good for students to take more time to focus on what they need. It also makes them more knowledge in their subject deeply.
First of all, learning in general subject may be a waste of time and the opportunity to access the careers they want. When there is a tutorial on a specific job and knowledge necessary for them.
