OK intro to some concepts, but it is very frustrating to me that if I don't run each solution exactly as the lab shows it, then I can't get credit. It discourages me from building my own solution because I am just forced to replace it with the "suggested solution" in order to receive credit. If you can answer the question correctly, it should suffice. Also, the first 3 questions in the lab have no associated data so there's no way to answer them other than guessing until you hit on the answer it wants!
