The Genius Girl

My stepmother secretly changed all my college entrance exam preferences to Lanxiang Technical School. She hoped this would ruin my life and keep me in the shadow of her precious daughter forever. But she didn't expect that gold would always shine. A few years later, at the International Mathematical Olympiad, I used my rough hands to write down the answers to the toughest math problems. I shocked the world, and everyone learned that the girl who expertly operated excavators was actually a genius.
