When you create a course, you can set the order in which the Trainee can access the course material.

• While creating a course, in the drop-down option Allow accessing Course material in: you can choose, Anyorder or Sequence.
• If Anyorder is selected, the Trainee will be able to view the course material, in any order.
• If Sequence is selected, the Trainee will only be able to view the course material in the order the material is uploaded. Trainee will not be able to view next module/content before completing the previous.
