Eyes glowing with excitement and oozing confidence, 96-year-old Karthayayani Amma, who scored 98 out of 100 in her Class 4 equivalent exam says, "I knew as long as I study I would score this. "The super grandmom from Kerala is the oldest ever, in the state, to take a literacy test and justifiably she flaunts her achievement. "I saw small children studying...I too had the desire to study. So when they asked me, I said why not! I want to study for the Class X equivalent but have just finished Class IV," Amma told NDTV.
