I am continually amazed on what pre-professional students waste their time worrying about. Do something constructive and just study. Whatever test version you get, you get. That's the nature of the DAT and all standardized tests. Test versions are probably statistically equivalent or the ADA would have to change things. Some people are better at reading the ethics passage while others are better reading science passages. So for the sake of yourself and the rest of us here, worry about something that matters.
