"No need, I have it." Zhang Ningzhi took out the test papers she bought, "Hey, do you want to try this set?"
"Oh, oh, thanks." Jiang Nian accepted it casually. After all, it was from Zhizhi, so there was no need to be polite.
"Hey, can I ask you a question?" Zhang Ningzhi bit her lower lip, looking a bit shy, then looked up and blinked.
"Go ahead, is it English?" Jiang Nian was puzzled.
"No."
"Biology?"
"Also no, it's Chemistry." Zhang Ningzhi looked earnest, her big eyes bright, not showing any ulterior motive.
Jiang Nian was baffled, not knowing what she was getting at.
"Which question?"
"Well..." Zhang Ningzhi took the opportunity before the end of morning study to pull a test paper from his drawer, "There are two major questions I don't understand."
"Oh, oh, point them out." Jiang Nian was interested too, explaining questions to others could also help him improve, "I've already finished them."
The test paper was spread out, and the surface was relatively neat.
