Since the last change in the portal there is not a way to determine which response was considered correct on a question missed. 
The system only lists the test questions and which responses were correct when submitted or incorrect by number and letter. A page number is also listed but in several instances my response was located on the same page as the incorrect response that I selected according to the auto grader.
It would be very helpful 
to be able to view the test with correct responses also so I can understand which response I should have selected.
