It seems difficult for the students to understand the rating system, especially the difference between grey and yellow stars.
A couple of suggestions which may help include:
A help button (question mark) to give an explanation.
A mouse-over tip to explain the stars
Showing the current and achieved rating, either in a mouse-over tip or alongside stars and bar
A mouse-over tip to show the threshold for each star.
The mouse-over tips could be good «first issues».
