Most Bible Quizzers should have pretty decent basic Bible literacy - after all, we already consider the Bible important in our lives. But do you really understand it beyond the books we directly study? If you're not sure consider taking this test to see where you stand. Have a friend or family member administer the quiz, and total up your score. It should not be a problem if you know a different translation of the Bible than the one used in the test.
If you find yourself doing less well than you expected, don't worry. There are plenty of resources at the church and among Quiz Teamers, to help you know the Bible better.
