1.Meshack Bradovic, CFA, was recently hired as a credit analyst at a credit rating agency whose major clients include publicly listed companies on the local stock exchange. One of the clients is currently preparing to issue a new bond to finance a major factory project. Analysts are speculating that without the new factory the company will not survive the onslaught of competition from increasing imports; therefore, the company is counting on an upgraded credit rating to enhance the subscription level of the issue. Bradovic’s research suggests the creditworthiness of the company has severely deteriorated over the last year due to negative operating cash flows. Without conducting extensive research, Bradovic’s boss puts pressure on him to upgrade the credit rating to an investment grade rating. What course of action is most appropriate for Bradovic to prevent any violation of the CFA Code or Standards?
A. Quit his position with the firm.
B. Upgrade the rating but note his objections in writing.
C. Disassociate with the credit rating report, the bond issue and the client.

答案是A, 但是我很纠结于到底a和c之间怎么去取舍？

The following ten observations are a sample drawn from a normal population: 25, 20, 18, -5, 35, 21, -11, 8, 20, and 9. The fourth quintile (80th percentile) of the sample is closest to:
A. 8.0.
B. 21.0.
C. 24.2.

答案是B，可是书上明明讲的是(n+1)*y/100这个公式，到底是谁对啊

1. The best action is to quit the position because the boss is not reliable person any more and you should seek other positions in order to maintain independence and integrity in this profession.

2. Arrange the data and do the counting by yourself, 80% number of the sample sould come a easy job. Moreover, when the number of data is even, the formular changes to n*y/100. Good luck next time!!!
