The Course Reinstatement Fee is the difference in fees between a course taken for Audit and a course taken for Credit, at the time of application for course reinstatement. For example… 
The fee for a 3-credit course is $450 taken for Credit and $240 taken for Audit. In this case, the CRF is $210. For a 1.5-credit course, the CRF is $105. 

A student who wishes to be re-admitted into a core course* for the sole purpose of submitting their coursework or assignments for grading can apply for course reinstatement. It is applicable only for students who have previously taken a core course on credit which remains un-graded due to non- or incomplete submission of course assignments by the respective assignment deadline(s) given. 

Under the course reinstatement, you are only allowed to do the tests previously not done and/or submit assignments previously not handed in for grading. Please note that the maximum grade for any course that has been reinstated is B+.
