 Things to watch out for:
   - not initializing a field ( fields are private, to encapsulate)
-  - accidentally making a local variable instead of initializing a variable
+  - accidentally making a local variable instead of initializing a variable in a constructor
-  - remember to make methods public, and don't forget to use () for the parameter list, even if there are none
+  - remember to make methods public, and don't forget to use () for the parameter list, even if there are no parameters
   - local variables are never public nor private
   - dangling else statements (p 148)
   - forgetting to have a method return something of the correct type
-  - not to add a System.out.print were no printing is requested (This can be a 1 or 2 point 'Extraneous code that causes side effect' penalty on the AP Exam)
+  - **Do not** add a ''System.out.print'' when no printing is requested (This can be a 1 or 2 point 'Extraneous code that causes side effect' penalty on the AP Exam)
-  - using local variables that you don't declare ( also a AP scoring penalty)
+  - **Do not** use local variables with first declaring them ( also a AP scoring penalty)
-  - changing a value referenced by parameter or destroying data in a parameter (also a scoring penalty)
+  - **Do not** assign a value to a parameter inside a method  (also a AP scoring penalty)
   - return statement on a constructor, or a method that isn't supposed to return something (a 'void' method).  This too has a AP scoring penalty)
 Finally, please remember to get a good night's rest and a healthy breakfast!
 Good Luck!
