@geetharao Nice to see so many interesting contests you are organizing:-)
I am glad to tell about one of my favorite teacher at South School, Volakad, Udupi. His name is Srikantha Dutta and we used to call him Dutta teacher. He was my science teacher till SSLC. I used to sit in front row. As we all know the front row is the hot seat and most of the questions from teacher is thrown to the first bench students. He used to pick me and couple of other friends regularly and ask some questions about the previous day lessons. I had no option but to read the previous day lessons and come prepared for the next day. Else, traditional punishments like standing on the bench or standing outside the class was inevitable.
Because of regular study of science subject, I used to score good marks in Science, where as in other subjects I used to score only average. For the final exam also I didn't have to study extra hard as all the lessons were already studied and memorized.
