Xiao's mother took Xiao Siqian shopping for clothes, bought daily necessities at the supermarket, and then took him to a bookstore to buy test papers from elementary school to high school.
Xiao Siqian stood by, watching his mother carefully selecting elementary and junior high school test papers, his mouth twitching constantly. He, a prestigious foreign university graduate, had to do these junior test papers.
Xiao Siqian endured and said, "Aunt, I've looked through these elementary and junior high school test papers, and I can definitely do them without any problem. How about we just buy two sets of high school test papers to see?"
Upon hearing this, Xiao's mother's eyes lit up, and she exclaimed excitedly, "Xiao Quan, you can understand and do these elementary and junior high school test papers?"
Xiao Siqian nodded.
Xiao's mother pointed to several questions on the third and fifth-grade test papers, and Xiao Siqian answered each one.
