1) Why Oracle even doesn't say, how much right answers I've got in the beta exam directly? Can't they calculate them right after taking the test ? I can imagine, that they won't score some questions, that nobody really understood?
2) Why do they need 11 weeks to post the results and passing score? I think it's a big time to wait.
3) What passing score could it be? I think something between 57% and 65%, looking at other passing scores.
Oracle needs to get the results of everyone who takes the beta test and then figure out which questions go into the pool for the real test. This involves easy/hard questions, topic balance, unclear questions etc. This involves human effort and does take a long time. Then they give you a score based on which questions you got that made it into the question pool. Giving you a score earlier would be misleading. And yes, it is a long time to wait. But the beta is inexpensive. The inconvenience is part of the tradeoff.
