"It's not realistic to improve quickly!"
Sun Xing shook his head while taking a puff and said, "High school mathematics is neither too difficult nor too easy. In your case, if you want to improve your math grades, you can only start learning from high school freshman year, beginning by memorizing basic concepts and formulas."
"If we compare mathematics to constructing a skyscraper, then basic concepts and formulas are equivalent to the foundation. Only with a solid foundation can the skyscraper be built..."
"So you're saying I have to read through all the textbooks from freshman to senior year?" Shen Qiushan flicked the ash from his cigarette and asked.
Sun Xing shook his head: "Going through them once isn't enough; you must at least memorize the concepts and formulas, like those you learn in freshman year: what is a set, what are sufficient and necessary conditions, what is a function, and what are the various methods to represent functions..."
