Hints and tips on using the resource...

Each topic stands alone. If you follow a link that takes you away from this site, the browsers' "back" button will bring you back. The "back" button on the screen goes back only one level, the browsers' "back" button comes back to this page. There are some built in self assessment tasks and links to other resources. To reveal the answers on the self assessment tasks you should click and move (swipe) the mouse pointer, rather like selecting text in a word-processor,  test your technique on the test button below if you want.
