Sometimes you just want to learn, and other times you want to test that knowledge against other developers. Let's face it: lots of humans like to compete, and we make it easy for you to do that with our weekly tournaments.
Each Saturday, we publish a brand-new quiz on SQL, PL/SQL, database design and logic (this list will likely grow over time). You have until the following Friday to submit your answer. And if you don't want to compete but still want to tackle those brand-new quizzes, we let you opt-out of ranking.
But for those of you who like to compete, you can check your rankings on the Leaderboard to see how you did the previous week, month, quarter and year. And if you finish the year ranked in the top 50 in a particular technology, you are then eligible to compete in the annual championship.
Note that we do not show the results of your submission for a tournament until that week is over. Since the quiz is competitive, we don't want to make it easy for players to share results with others who may not yet have taken the quiz. And since the quiz is competitive, we also have rules against cheating. Read Competition Integrity for a description of what constitutes cheating at the Oracle Dev Gym.
