Did you register for the class through Instant Enrollment?
Upon completion of a course, you will receive a grade from the teaching college. During the instant enrollment process you consented for this grade to be sent back to the home college automatically. No action is required.
Did you apply to the teaching college and register for the class through the teaching college's website/portal?
Contact the Admissions and Records office at the teaching college and request that transcripts be sent to your home college to transfer those credits.
