A week or so ago, Google posted a webmaster quiz for people to answer. Today, they posted the answers to the quiz. The beauty of this is that you can really learn a lot about Google's SEO best practices by just reading the questions and answers.
You can read all the questions and answers or see how well you did on the test, if you took it.
Only three people got all 40 questions correct, they include ChrisRaimondi, theopeek and beussery from the forums.
