Do we know the duration of the course on SDL Academy, and do we have a deadline to meet?

The latest invitation for the SDL Academy course on SmartQuery includes this statement:
"It is imperative that you complete your training so that you are fully qualified to use smartQuery. Your line manager, will be contacted if you do not complete the training."
It would be good to know what the actual deadline is and how long the 13 modules will take so that a proper planning is possible within our teams. Does anyone have these information available?
