"I took a look at them. The past years had most of their questions about mathematical analysis and advanced algebra. Each occupied thirty percent of the questions."
When Yun Xiangxiang came back, Song Mian drew a pie chart for the ratio, "Analytic geometry takes up fifteen percent of the questions, while functions, limits, calculus, and infinite levels all add up to take fifteen percent."
Yun Xiangxiang listened carefully. She raised her head when Song Mian paused. "What about the remaining ten percent?"
"This ten percent would be the variable," Song Mian gave Yun Xiangxiang the past questions.
Yun Xiangxiang discovered that she could not fully answer them after perusing it, "There are blind spots in my knowledge."
"They are comprehensive questions. These test you on how much work you did outside of class, as well as problem solving," Song Mian jotted down a question mark here.
