At the university of Calgary:
Academic Probation

Students will be placed on academic probation if they have achieved a grade point average of 1.70 or greater but less than 2.00 on all courses taken since their previous review.

Students will be permitted a maximum of one probationary period while registered as undergraduate students at the University of Calgary. Students will be required to withdraw rather than be placed on probation for a second time. Probationary periods that have occurred in excess of five years previous will not be counted.

Students will normally be required to withdraw from the Faculty if they:

(a) have achieved a grade point average of less than 1.70 on all courses taken since their previous review.

(b) have accumulated a total of five or more full-course equivalent "F" grades.

(c) have achieved a grade point average of 1.70 to 1.99 and have previously been placed on probation.

(d) have accumulated more than five full-course equivalent course withdrawals.

Students placed on probation or required to withdraw will be so advised in writing.
