At any moment, you will sigh, "I thought it was a bronze, but it turned out to be a king."

When I was in high school, my deskmate didn't study very hard. She often read novels and played mobile phones in class, but he did better than me in every exam. I thought he was a bronze, but he was a king.

afterwards, I learned that he is very scheming. Every time he takes an exam, he will observe the students with poor grades and exclude others' choices. This will improve his accuracy and his natural score. He is simply too smart.
