英语：
1.考试紧张，大脑一片空白；考试比平时练习差很多。

2. 现实生活的preparation。
3. root的含义，没有深入接受gods teaching。

退课原因：
The textbook is a very classic linear algebra book. It is very helpful and I read almost half of it. But I found the professor's accent is difficult for me to understand. And there is no TA office hour. We have homework every week.

I think I will have better way to learn linear algebra. There is an online open course offered by MIT. And I can also learn the part which will be conducive for my research.

In the following semester, I plan to take courses that have projects along the progress.
