是我英语太差了吗，为什么我觉得for each book in their order既可以修饰additional shipping fee也可以修饰fixed processing fee and additional shipping fee呢？

嗯最恨的是看着C选其他答案！最后没时间导致😭
基础知识、解题思路都有，真正导致结果不理想的因素有：对题意理解的速度慢、细节不注意、计算推导不够快、时间紧迫感导致的慌乱、以及慌乱后导致的不check，选项混淆

statement (2)
just pick various numbers whose lcm is 30.
notice the numbers selected above:
5 and 6 --> remainder = 1
10 and 15 --> remainder = 5 > 1
insufficient.

+1因为紧迫感，将正确答案的选项混淆，也没check！

+1 第一次Prep模考一直充满时间紧迫感导致：通项公式里是相乘，算到演算纸上却变成了相加，华丽丽地后面全推导错误
