First please gather the information you need, such as the learner name and the course you need to remove.

It is best to remove course by course instead of removing different courses from one learner.

Click Enroll Courses

Find the course you wish to remove then click the blue enroll button.

Click remove on the learners row. Example - I am removing Example User from Concussion Awareness course.

Are you sure you want to cancel the enrollment of this user, click Yes.

I hope this helps!
