Some of our homework tasks have videos to help you. You can find these by clicking on the Video help button at the top of the question page.
You can choose which video to watch from the list. Some question pages have a recommended video. If not, you can just choose the video that matches what you need to know.
Not every homework task has video help available but you can always get help from the matching lesson. You can open the lesson from any question page using the Menu.
