Xi Yan also had her doubts when she first saw the results, but unlike everyone else in the room, she wasn't one to jump to conclusions. Instead, she personally took their test papers and compared them herself.

Lin Xin had taken a more "innovative" approach in tackling her questions. Some of the steps weren't even part of the discussion, making her paper look even more tedious than neat. Fortunately, she had reached the correct answers.
Her students didn't disappoint her. They truly did pass the exams on their own.
There was no cheating involved.
