# Statistics

See also "Mathematics".

Students should note that in the Science Faculty the minimum acceptable grade in a course which is required by a particular program or is used to meet a prerequisite, is a "C". Any student who fails to attain a "C" or better in such a course must repeat the course (at the next regular session) until a grade of "C" or better is attained. Students will not be eligible for graduation until such deficiencies are removed. The only exception will be granted for a single course with a "D" grade that is a normal part of the final year of that program, and is being taken for the first time in the final year.

STAT 2*** courses may not be taken by students who have passed a higher level STAT course.

See Courses-> Saint John or Fredericton -> Standard Course Abbreviations in the online undergraduate calendar for an explanation of abbreviations, course numbers and coding.
