107% in a test?

Hi, can someone explain the test-case for this question?

It says that

  ryerson_letter_grade(107)

should be A+, but this makes no sense. The input parameter is the "Grade percentage" - which can't be more than 100%! Also, the question statement mentions the grades are "...as defined on the page Ryerson Grade Scales." But that page says A+ is 90-100%! Could we get this test-case changed?
