She, with the help of her brother and another family member, crossed the swollen river Champavati, risking her life.
A video of the woman wading through neck-deep water with the help of the duo has gone viral on social media.
The incident occurred in Gajapathinagaram mandal of Vizianagaram district. Taddi Kalavathi, a resident of Marrivalasa village, had to take an examination in Visakhapatnam.
The river was in spate due to heavy rains upstream, cutting off the village. There were no boats available to take her to the other side of the river.
With no other option left, the girl entered the river. As she did not know how to swim, her brother and another family member carried her on their shoulders and helped her cross the river.
