Hotlists are easy to use:
Click once on the title you wish to use (such as 'General ESL Skills'). This will open the Hotlist. There are several categories listed: Reading, Grammar and Speaking and Listening.
Under each category are several Websites your teachers have chosen for you.
Click on the underlined words of the title you want to try, and it will take you directly to that Website.
Once on the site, you can follow the instructions for using anything on the page. The same information holds true for using the math and reading Hotlists.
