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

When I was in high school, my deskmate didn't study very hard. She often reads novels and plays with her mobile phone in class, but he is better than me in every exam. I thought he was bronze, but in fact he was a king.

I learned afterwards that he was very scheming. Every exam, he will observe the students with poor grades and rule out others' choices. This will improve his accuracy and his natural score. He is simply too clever.
