14th About the End of this Semester

It is almost the end of the semester. I am very happy and also kind of sad about this.
I am very happy because I learned a lot of thing during this semester's study, either in the ESL's writing class or in my other academic courses. I am very happy that I could get a approximately 3 weeks break after this whole semester's study. I am very happy that I could go back to China again in just one week, and I could see my families and many of my dear friends who did not choose study aboard like me.
However, every has two sides, I still have something not very happy at the end of this semester. Firstly, I think I didn't do my best in all my courses. I think I couldn't get a very good grade in my Plant Biology's class because I didn't really tried my best. I thought this class is so hard, and I kind of gave up at the very beginning. This is sooooo bad. Besides, I am also sad about that I may not going to see everyone in my writing class so often in the future. We have a very big campus here, and I know when we don't have a same schedule we can know see each other usually. I will miss all of my classmates.
