If your professor is using LessonLink and you correctly followed the special URL your professor provided to you, your professor will see your scores by viewing their LessonLink Dashboard. You won't have to do anything. However, if you did not use the URL that your professor gave to you, they will not be able to see your score.
If your professor is not using LessonLink or you did not use the URL that they provided, you can still show that you've taken a CALI Lesson by printing off the CALI Lesson Certificate. Please view the FAQ on CALI Lesson Certificates for complete instructions on how to print or save them.
