Your academic record only records whether or not you successfully completed the CARS unit, not the exact score you got on the quiz.  You will either get a 'UP' (Ungraded Pass) or 'NC' (Not Complete). 

A 'UP' grade indicates that you completed the unit successfully; a 'NC' grade indicates you did not meet the requirements of the unit.

All grades for CARS are uploaded to students' academic records after the unit closes. While the CARS unit you are enrolled in is open, you can view your grade at any time using the Your Grade link in the LMS menu.
