Learning paths are simply a bundle of courses or quizzes.
To access a learning path, simply navigate to the Learn section of your Learning area. Learning paths are labelled as such. You will be able to see the different courses and quizzes that make up the learning path from the card it self.
Click Start to access the learning path.
Once in the learning path, you will notice a series of training items. You will only be able to access the first item (or the one you most recently completed). In order to proceed along the learning path, you need to complete the first item that is accessible in the list.
