Input:  Person1:     Hey John , did you register for classes yet ? 
 Person2:  I register this Friday . 
 Person1:      What classes do you plan on taking ? 
 Person2:  I really want to take the communication class , but I don't know if it will be available . 
 Person1:      Is that class really that popular ? 
 Person2:  Yeah . I tried to get in last semester , but it was full by the time I registered . 
 Person1:      What other classes are you going to take ? 
 Person2:  I still need to take English 201 , but I really don't like writing . 
 Person1:      I took that class already . There is a lot of writing , but it's not that bad . 
 Person2:  Oh really ? Who was the instructor ? There are like 4 different instructors to choose from . 
 Person1:      I had Professor Mahoney . 
 Person2:  Is he an easy grader ? 
 Person1:      I'm not sure if he is or not , but I thought he was definitely fair . 
 Person2:  Do you mind if I ask you what you got ? 
 Person1:      Not at all . I got a 3.8 . 
 Person2:  Well , what did you get in English 101 last year ? 
 Person1:      I got a 4.0 in that class . 
 Person2:  Well , I can't compare to you . I got a 3.1 in English 101 . That means if you got a lower grade in English 201 , it must be harder . 
 Person1:      It's not what it appears . I actually tried harder in the 101 class . If I put as much effort into the 201 class , I would have received the same grade . 
 Person2:  Oh . That helps . Thanks .
