Once signed in to Google Chrome with your wccs Google Account, your bookmarks sync between the devices you use. This means you can add bookmarks on your PC at home or in the classroom which will then be available everywhere you sign in.
The easiest way to add a bookmark is to drag and drop the URL from the Chrome address bar (Omnibox) directly onto the bookmark bar. If your bookmarks bar is not visible you can show it by pressing <Ctrl>+<Shift>+<b> or use the menus as shown below.
You can add folders to organise your bookmarks bar by right clicking on the Bookmark bar and accessing the context menu.
