Subject: The Exam

The exam problem titled "Expression Evaluation" is not
related to the slides titled "Expression Evaluation". 
Well, not much related...

However, the exam problem titled "Grammar Rules" is 
related to the slides titled "Expression Evaluation",
in so far as both of the use grammar rules.
