Senior high school's world

I am unbelieve when i come a senior high school's word.

I think  senior and junior are same, but when i face a senior's word
That's really different....

Many things are different, They are
1.) Many homeworks and Nothing tolerant. 
     If you don't do homework, you won't pass.
2.) Teachears are dicipline, If you late, you can't join lessons in time.
3.) Your friend can stole ur book/borrow ur book to see ur homework
4.) And..... lazier than before to do that something
5.) Extremely tired!



I hope i can join all activity  in senior high school
