I've added some questions to the code for TicTacToe that you should be able to answer when you talk about Project 7c. The questions are comments of the form

-- ?? <Question>

Please prepare your thoughts in advance. But don't come with a written sheet of answers. I expect you to explain the answers in your own words, not read me pre-written answers. 

As you know, my concern in the reviews is that you understand the material, not that you can say the correct words. If your answers suggest to me that you are simply parroting memorized answers, I will press you more deeply to explore your understanding.

One way to convince me that you understand the material is to explain it to me as you would explain it to a 10-year old. Find multiple ways of getting the point across. Draw pictures and provide illustrative examples.
