This might be obvious to all, but...

If you really want an overall feel for pass/fail scores from June 07, go to page 80-87 on this forum and there is probably 50-100 fail/pass scores from that period. I myself use the 47/66/77 rule in calculating the scores, and besides 1 or 2 stragglers, even when that more conservative rule is used, it seems a 66-67% is a passing score. It was very interesting going through, some I can tell just quick was PASS or FAIL looking at the distribution. The borderline ones I ran the calculation for.
