Hi Lori,
You can go to each lesson and click on report tab. It should show the date and time started and completed and the time taken to complete for each user. If you want to have one place where you can see the grade and the attempt date for all lessons, you will need to install a configurable report plugin (https://moodle.org/plugins/view.php?plugin=block_configurable_reports) and create a new custom report. You will need to have a basic mysql programming if you want to have this custom report.
Hope it help,
Adrian
