In most ways, what you see as you create a course is what your learners will see as they take the course.
To see exactly what your learners will see from the course management page, click the drop down arrow on the "edit" button. Then, click “view as learner”.
You may also enter learner view from inside the course as you edit.
The main difference between the author and learner view is the absence of the gadget tray.
