Introduction

 39C class is really a big challenge for me. I know I am not a good writer, I started my writing classes from AE 20A, which means I was the worst writer at the beginning. I used more than two years to take the writing classes, and now I came to writing 39C. 39C class is really a challenge and difficult class for me, I never write any research paper not only in America but also in China, so it is a totally new class and knowledge for me, but it is very useful.  After I studied writing 39C class, I think this class is very helpful, it will not only help me in future upper level writing classes but also help me in my other classes.
