In this test, you have to identify all the s amongst a list of words that you see on the screen. The words will appear one at a time and you have to spot the s amongst them. The problem is that each word appears only for a second on the screen, and you have just one second to choose the (or not) before it disappears.
Below the words is the button that you have to click to choose a word. Click on the button if the word can be a , or leave it if it can't. You get a point for every correct button click up to a maximum of 20 correctly identified s. However, you lose a point if you click on a word that can't be a .
