Speaking English Like an American -- Lesson 3 
Ted tells his parents he did poorly on his Chemistry test. They tell him he needs to get serious and study more.
Susan:   How was your day at school today, Ted?
Ted:      Bad. I had a Chemistry test, and I 
blew it.
Susan:   Maybe if you didn't 
cut class so often, you'd do better.
Bob:     That's right, son. Stop 
slacking off and 
start hitting the books.
Ted:      But I 
can't stand Chemistry class. Besides, it's 
a lost cause. That class is 
way over my head.
Susan:   You need to 
buckle down.
Ted:      When I'm a famous musician, people won't 
give a hoot about my knowledge of atoms and molecules.
Bob:     That's 
beside the point.
Susan:   We know you have your 
heart set on going to New York University.
Bob:      And you don't 
stand a chance of getting in there with such poor grades.
