If you select Templates when creating a course, you'll be presented with a few different templates to pick from:
Fixed order or adaptive?
An adaptive template will change the difficulty level and the content that a learner sees as they move through it. Here's an outline of how an adaptive course works:
Sometimes, however, everyone needs to see the same information in the same order. If that's the case for you, pick a fixed-order template.
Small or large?
If you have 12 or fewer learning objectives you’d like to test on, start from the small course templates. Large templates are set up to include as many as 20 learning objectives.
