老师好，我1712的时候考过一次，没能考过。想请教一下，1812相对1712是否变化比较大？另外，1806的课程和1812的课程内容会有变化吗？是否可以现在就根据1806的基础段课程开始细致的学习？

您好，我想请问一下这个13题目 中的 asset turnover 为什么变大不对？ 为什么回变小呢

Which of the following statements about risk-averse investors is least accurate? A risk-averse investor: A seeks out the investment with minimum risk, while return is not a major consideration.
