 Person2:  Let's just go over all of it to double-check .  
 Person1:      Sure , let's do it .  
 Person2:  Here is the answer sheet . Do you see a place where I marked something wrong that should have been right ?  
 Person1:      I don't see any mistakes .  
 Person2:  OK , now that we've gotten those straightened out , let's total the score .  
 Person1:      Yes , let's total it .
