I'm somewhat biased as I built the site, but https://sasensei.com is a great place to test your SAS knowledge, not least because the questions / answers all come with explanations - so you can understand why it was / wasn't the right answer.
Furthermore, each question is peer reviewed, so you are unlikely to find incorrect answers (like some of the examples out there in the wild web).
Once you have amassed enough reputation, you can take short SAS quizzes (12 questions) and measure yourself against others.
Finally, once you have green belt, you are able to submit new questions. Writing SAS questions (with explanations) takes a fair bit of thinking, and so it's actually a great way to revise! As well as a way to earn tokens that you can re-use for more quizzes.
