My busy week. I was really busy this week.Since the new students was coming at 20th this month, the student union organized lots of students to receive them,and I was a member of them.I received new students for about two days,my job is easy but need many time.So after two days receiving I felt a little tired.Because I have switched my major since this semester,I need to get my freshman year credits by studying with freshman students,and I also need to take sophomore lessons,so my courses in this semester is more,and the homework is more too,which makes me busier.
