The English exam in the morning was self-explanatory, being Qiao Yu's strong suit. The physics and chemistry in the afternoon were also quite simple. The real challenge was actually with history and moral and legal studies.
Although the last two subjects were open-book exams, finding ready-made answers in the books was actually quite difficult once the difficulty level of the questions was raised. The most typical was reading materials and answering questions.
For example, an excerpt from "Huaxia Culture General History" about the spirit of valuing "harmony" in "Zhou Yi" was given, asking for the Taoist and Confucian views on the spirit of valuing "harmony". Then two ancient pictures were provided, asking to combine learned knowledge to list two historical facts that reflect the spirit of valuing "harmony" in the formation and development of Huaxia's ancient unified multi-ethnic states.
This made Qiao Yu, who hadn't paid much attention in class, feel a slightly throbbing headache.
