How Come Gu Ning Became the Champion?

The title was: How come Gu Ning became the champion?

Many people left comments with suspicions on the fact that Gu Ning had won the competition with full marks three times. Some believed that Gu Ning had bribed the Education Bureau to get the correct answers even before the contest began.

"It's said that Gu Ning is an excellent student in her school, so it isn't a surprise that she won the first prize, but how did she manage to do it with full marks? It has never happened before. I can't believe it."

"I agree. My uncle is a math teacher in a high school, and even he can't finish those exercises within such a short time. Gu Ning is just a high school student. I don't think she's able to do that on her own. She's a successful businesswoman now, and it might be easy for her to get the correct answers beforehand."
