The only superpower she has in her teaching is her way of speaking. It is so smooth and crystal clear.

[sanadrai]

Thank you ma'am very much you helped in class 11th and now in 12 th thanks a lot☺️

[way_to_high]

Now I understand why I like studying from learnohub, , they provide us the practical knowledge by some mini animations which help us to imaginate the things and also the examples make us real easy to understand the concept.
Thankyou mam❤
