My science teacher handed out group homework thatwe have to do with excel program until the next day when I was a high schoolstudent. However, it was difficult for most my class students to do thehomework because we first used the excel program and did not have enough timeto do the homework after school. Nevertheless, we could do the group homeworkbecause it was possible for us to do the assignment by using a messenger likethe facebook that can share our idea and information of excel program withoutany fee until before we went to our beds.
