Above all, I want to thank my TA, APalley, he is really patient since he answers my stupid questions and makes detailed comments on my codes which help me a lot to refine my codes and make progress. The course is divided into several levels thus it is clear for us to figure out what to focus on and helpful for us to become skillful through tiny steps. Needless to say, the professor is experienced in teaching, with graphs to illustrate his points vividly. As for the forum, it is really useful for finishing the homework and gaining some extra information. In addition, the forum pushes me to improve my skills of searching for information and reading materials. To sum up, the course is a brand-new experience for me, a Chinese student, as well as a significant step in my pursuit for a career of quant.
