In the NROC Course Manager, go to the Reports tab and select the Unit you want to view from the dropdown list.
In the Review column, click on the score for the student you want to see.
This will open a dialog box like the one below. Here you can see their score on each learning objective.
Click on the "Open Summary in Player" link.
Here, you will see the same screen students see at the end of the Review. At the top is their score, followed by a breakdown of attempts per question. If you scroll down, all of the questions are listed individually and each one is clickable. You can see how many attempts they made on the questions, and view the student's answer by clicking on the question number.
