It is simple to find the study library in your WordGo app, although only group guides, or those studying alone will be able to change the study.
First you navigate to the 'Group Details' icon which is the second from the left at the bottom of your screen.
You then select 'Course' and scroll all the way to the bottom to tap on 'View course library.'
You can browse the available studies and tap on one to open up a helpful description. Once you have scrolled to the bottom of this you can select 'Start Course' or go back to the study library to find a different course.
If you have any further assistance please raise a ticket here to contact a WordGo customer support agent.
