Well, I want to ask, how much did you spend on the materials and teaching AIDS you bought in junior and senior high schools? Sophomore parties can also answer.
Me, grade three. Not long after the beginning of this semester, I bought two materials for seven courses, except for three books on mathematics and a big newspaper (this is the first round of review), and I have spent more than 500 yuan. After the second round of review, I have to buy various test papers, and then I have to buy the third round of review.
