$\text{Some hints and tips about the HTML5/JS applets:}$ 

• After selecting the desired applet, a Wiki description page appears with a short summary of the content and an user interface.  At the beginning and end of this description page there are links to the actual HTML5 applet.
• The HTML5/JS applets can be rendered by many browsers such as Firefox, Chrome and Safari, as well as smartphones and tablets.
• The exercises and the solutions are integrated into the applet.
