The exam divides its questions between fifteen hundred to seventeen eighty-nine and seventeen ninety to eighteen seventy-seven, weighting the later period at seventy percent.
In practice
This course's entry counts distributed to match that split exactly.
Where people slip
Units 01 to 07 average thirty-three entries and units 08 to 16 average sixty-one. That asymmetry is the design and not an accident.
