The last one is really hard. . . Did you understand the answer after reading it? . But I think I got seven points. . . I don't want to move.

This year's mathematics synthesis, the amount of calculation is definitely the largest, the second from the bottom, and there are a lot of miscalculations. And solid geometry. . It's harder to calculate than before. . The rest is simple, really. . . I was blinded by the last line at that time. . Originally prepared 150, but only got 138. .

I hope you will try to calm things down. That's all that matters. If it's hard, give up and go back and check. . I didn't check the wrong choice.
