This week's book giveaway is in the Python forum. We're giving away four copies of High Performance Python for Data Analytics and have Tiago Rodrigues Antao on-line! See this thread for details.
John,
You're right. Good eye! I've added this to the errata.
Note the mock exam questions change in order every time you take it so no need to give us the numbers. I have a file with all the questions for each exam so I can search by keywords.
