Note: The key thing to know here is that you must go into a Zone before you can take any Modules. Different Zones usually have different Modules.
To find your Modules:
Under a tab select a Pathway from your list (Note: your list will look different to this one).
Module Pathways have the small 'book' icon.
In the Pathway page that opens, choose your Module by clicking on it.
The Module image and description will help you find the correct Module.
Press Start to start this Module.
