I am a hindi teacher teaching in local system for past 4 years. As a teacher I have helped many kids not only to improve their grades but also their understanding of the language.
According to me, the most important part of any language is its grammar. My classes focus on building the grammar base( tense, gender, vachan etc)for the kids, rather then just practicing compositions without any understanding of the mistakes they make.
If your kid faces problem with the language, I will be happy to help.
