Hi, I'm Sohini

Hi! My name is Sohini, a friendly and helpful tutor currently studying Maths at the LSE because of how much I love the subject and teaching it, so I would say that I major in Maths. Nevertheless, I have always enjoyed learning and teaching languages to others, in particular Spanish, French and Bengali. To quickly describe myself, I am 21-years old and have worked as a tutor for approximately 5 years now.
