The Sim tracker allows you to choose a sim in the top drop down box, and see all the user data for that specific sim (this can be filtered by groups and subaccounts too). All the specific sim activity is grouped into one row, so if the user has done multiple attempts, you can find the result of each of those attempts by clicking on that row of the user, which will take you to the Activity Tracker.
You can add a date range here to filter the users that have been shared your sims between those dates. Be sure to click "show results" once you have inputted a date range.
Opposed to this, you can filter the users that have attempted or completed a sim within this date range.
This will remove any date filters from both the Date Shared and Activity Date fields, resulting in all the reporting data for all your users to be shown here.
