**Participation:**
The exam was written by 179 students,
although 189 had registered and paid the non-refundable fee.
Among the 179 students who wrote,
166 earned a raw score of 10% or higher.
All statistics that follow refer to this group of 166.

**Summary:**
Of the 166 students discussed below, 110 earned a score of 50%
or better.
In other words, 66% of the participants passed the
test and are eligible to claim credit at a sponsoring university.
The median grade was 61%.
(These scores reflect a modest upward scaling.)

Scores of 85% or higher were earned by 19 students; scores below 30% were recorded by 14 students. There were six raw scores above 85%: scaling boosted these into the 90's.

**Details:**
For each question, the following table shows
the scores that separate the participants into
four equally-sized groups.
The median score divides the group in half;
quartiles 1 and 3 bisect the lower and upper
halves again. Scores are reported using
percentages instead of individual points to make
comparisons easier.
