 #### Student outcomes
 
 A student should be able to:
 
-1. add more advanced elements, like tables or images
-2. handle multiple windows
-3. show error and warning popups
-4. use different forms of IO, like keyboard, mouse, or touch pad
-5. explain basic of fonts and accessibility
+1. Explain the differences between the big five, namely, copy constructor, move constrcutor, copy/assign, move/assign, destructor, and constructor.
+2. Construct a initializer list and explain conditions when it is necessary
+3. Delegate to the constructor of the base class
+4. Demonstrate and explain safe memory handling using shared or unique pointers
+5. Define what RAII is and the role of the constructor 
 
 #### Caveats
 
-*  programming user interfaces is rather complex and might not applicable for most students
+* Order of construction should match the initalizer list order
 
 #### Points to cover
 
-* More advanced API calls and design patterns
+* Not calling virtual functions from the base class
+* Do not initialze data outside of the constructor (two face initialization)
+* Difference between assignment and deep copy
