Once a module has been completed (i.e. all requirements have been fulfilled) then you can use the completion of that module as a Prerequisite to allow access to subsequent modules. To set prerequisites for access to a module, follow these steps:

Select the three-dot menu in the title bar of your module and choose Edit.
In the Edit Module Settings dialogue box, choose the preceding module to be completed as a prerequisite for the current module from the drop-down box.
Click + Add prerequisite if you want to have multiple preceding modules as prerequisites for the current module.
Remember that you can add requirements for completion of the current module (described on previous page) if this module will serve as a prerequisite for subsequent modules.
Note that both the Prerequisites as well as the Completion Requirements for this module will be displayed in the title bar of the module.
Select Update Module to save your changes to the module settings.
