I studied at Vidya Mandir in 11th / 12th. Though at the time I won’t have admitted it, Sarin sir really was and is the best teacher I’ve ever seen. All the forced homeworks and calls to my parents really were for the better. I learnt not only how to study for my exams but also how to enjoy what I study. He made everything so simple. By my definition he certainly is the ideal teacher. He has the sharpest mind I’ve ever seen and an amazing memory.
