Blocks are the column on the right hand side of our Moodle pages, usually consisting of the Latest Announcements, Tutor Contact Details, Progress Bars, and others added as required.
The Blocks column can be hidden or shownby clicking on the small arrow on the top right of the page.
Note: Moodle remembers if a user has hidden blocks or not so, it can create a little confusion for the user if they have previously hidden them and come back again after a while and cannot see them.
