Math Tutor Needed
In other parts of the world, most parents will typically hire a professional tutor and pay for this outside of school to provide their kids with help with their homework. In the U.S., on the other hand, many kids will study in groups or with their friends after school and teach each other.
It is quite common for a fellow classmate to teach or tutor another peer and earn some extra money on the side. I personally have done this in both high school and college. It is a great way for kids to study together and practice learning from each other instead of constantly working with a teacher.
