Can I stop in the middle of a CALI lesson and return to it?

Yes.  Scores are automatically saved when you take a CALI lesson.  To resume:

1. Log into the CALI website.
2. Hover over "CALI Dashboard" so that the drop down menu appears.
3. Click on "My Lesson Runs."  This will take you to a page that will list all of your CALI lesson activity.
4. Click on "resume" for the lesson you would like to resume. It will return you to the spot you were at when you quit the lesson.
