I need to use an anchor point for page that is too long?

Hi, I am hoping you can help me. My now you probably know I am a designer not a developer so when comes to code I have trouble. Basically I have page that is long and want to make sure visitors know to scroll or click to see all the content. The url is http://www.uych.vic.edu.au/first-aid/ and as you will see the this page has 3 courses so it is too long. Do you have any suggestions on how to ensure the visitor knows that there is more content?
