My preliminary, unconfirmed results indicate a PASS
I appear to have done well on the afternoon session, scoring 70+ percent on 8 out of 10 item sets (1 was 51-70% and 1 was <=50%). This implies a maximum possible score of 92%, a minimum possible score of 73%, and an average score of 83%.
My morning session results were worse than expected. 4 out of 11 item sets were 70+ percent correct, 4 out of 11 item sets were 51-70% correct, and 3 out of 11 item sets were <=50%. Using the appropriate points per question (which range from 14-20pts), this implies a maximum possible score of 75%, a minimum possible score of 43% and an average score of 59%.
In total, including morning and afternoon sessions, the greatest possible maximum score is 83%, the smallest possible minimum score is 58%, and the mean score is 71%.
My guess is that I scored around a 75% +/- in total. My minimum formulas assume 0% for <=50% categories which is a rather harsh/conservative assumption. If I were to use 25% (the midpoint) instead of zero, that immediately brings the total overall average to 73%.
