|1Indicates that student transcript records did not list any recognized mathematics courses; however, these graduates may have studied some mathematics.
|NOTE: The distribution of graduates among the various levels of mathematics courses was determined by the level of the most academically advanced course they had completed. Graduates may have completed advanced levels of courses without having taken courses at lower levels. Academic levels are labeled according to the most commonly known course at that level; courses with different names or on topics of different but similar academic difficulty may be included under these rubrics. See supplemental note 12 for a complete listing of all the courses classified at each academic level. Detail may not sum to totals because of rounding.
