Anyone taken CSU Global's - Organizational Development CBE?

[gremlinbrawler]

Just looking for some feedback. I'm working on the pre-test now and it seems very easy with a lot of true or false questions but I know that the real test might be harder. Any feedback on what to study and the difficulty of the test would be great.
I know that I have a free retake but I'm still a little worried just because I'm not used to needing 70% on exams and if I did fail twice then I just wasted $250!

Thanks

P.S. I will also be taking the Conflict Management CBE next so if you have any feedback on that one, it would be helpful as well.
