I passed as expected as well. This was my first time taking a beta exam, and the only thing I didn't like was waiting for...(checks watch)...6 months and a few days for my score report. I had a pretty good idea where I scored well and where I may have needed more work on test day but didn't get to check for surprises until this morning. Normally I'm not surprised at all by the items I've missed when reading a score report, but since I didn't study in advance for this one I may have missed some items I'd normally consider strengths.
I wouldn't hesitate to participate in another beta. While the exam was longer than usual, I don't recall it feeling repetitive nor wandering into trivial 'gotcha' sorts of questions, which says a lot for the quality of the question pool that was developed.
