We use this path for individual users/courses:
Go to any course and click down to the page where you see the Enter button to start the course. Instead of starting the course, look at the top of the page. There are two rounded tabs near the middle top. The one you'll initially be on is the Info tab. The one next to it is Reports. Click on Reports.
You'll now see there are three different reports; Basic Report, Graph Report and Interactions Report. Below that, you'll see an alphabetical way to pare down the list of enrolled users shown. You can also scroll down to the bottom of the page and change what types of users you want to see from a drop down list. The default is to show all users. The other choices are "Users with no attempts only" and "Users with attempts only". Pick the one you want to see and then click Save Preferences. (This preference save is only for the report you're currently viewing and only for your user account. It goes back to the default when you navigate to it at a later time.)
Choose to view "users with attempts only" and click Save Preferences. Now you have a list pared down to a more usable amount. Scroll back to the top and you'll see all the people who have opened the course. This list scrolls from side to side as well as up and down. It's pretty wide. As you scroll to the right, you'll see more columns of info. Among those are; Attempt, Started on, Last Accessed, Score.
If you click on the number "1" in the Attempt column, you'll see the total time for that attempt and a link called Track Details. Clicking Track Details will show you a long list interactions that were saved as the person was making their attempt.
