Tutors teach different subjects to students depending on their education level. They may work in short bursts or at a regular, more extended cadence. They may work for schools, in specific grades, or for smaller groups or individuals. But tutoring is not just about particular subjects; it is also about developing a love for learning. If you are an enthusiastic person, are kind, empathetic, and know how to teach people to be the best versions of themselves both in the classroom and off, you are likely to be a great tutor.
Tutors who tend to have the best results with their students also tend to know the subject they are teaching. But a person who is smart and has knowledge in one subject could indeed teach a different one if they work at it. A tutor must also always provide positive feedback to students to encourage them.
