Zi Lingxi shook her head and stopped thinking about it. Then, she went to the next classroom with Cha Qing Luo and the others.
The second major class was advanced mathematics.
Even people like Zi Lingxi and Cha Qingluo were a little confused by the advanced mathematics class.
It felt completely different from high school mathematics.
It wasn't the kind of logical question solving, but the kind that required one to remember some concepts.
Moreover, the teacher's lecture was very fast. In one big class, he had already covered several sections of content, not giving them any time to digest.
Therefore, everyone was listening quietly during the class.
Liu Ningning took notes as she listened.
She wasn't the particularly smart type, so she could only work harder than others.
The class ended very quickly.
It was already noon when class ended.
After class, Zi Lingxi and Cha Qing Luo prepared to go for dinner.
