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.
