Students of doctray can teach on basic level as well as degree college level giving real life examples to make students clear the basic concepts.

I think karnika ma'am is a trustworthy teacher because I use to leave my child at her place for one hour tuition but until and unless the topic which she is teach doesn't get finished she did not stopped teaching. Also she has a vivacious wibe to her.

Because she is a great scholar and a trust worthy person .
