Mr.Chadd is a modern way to help students with their school. A lot of children have difficulties with planning and doing their homework, this can be a problem just because of the time it takes, but also because they need some extra care. This care can be in the form of a person who checks what must be done or simply a sparring partner to some extra time from a professional coach of the subject.
Most companies that help students/children with these tasks are traditional and work with someone who comes at your house or you go to a designated place. Mr.Chadd works a little more modern: they offer help through a website and app. The coaches that work at MrChadd are mostly young students in the right field, but are qualified to teach younger people. The advantage of using students is that they have recent memory of the subject and can relate to the world of the younger people who need help on the subject. And both are of the app-generation so they know how to message eachother and use the app.
so if you need some tutoring or extra help with your homework, take a look at Mr.Chadd.
