If you are creating a drill or story, it is useful to sometimes check what the end result will look like to the participants. You can check if question settings are correct, but also if the text or media looks good in the player.
 

The text you enter, can sometimes seem very long. If you then preview the question, you can see if this also applies in the player and needs to be adjusted. It is also possible that you forgot certain settings that you will encounter in the preview. Always make sure that you preview a question, the whole drill, or story, before you let your participants practice. This prevents unnecessary mistakes.

Previewing the entire drill or story is very easy. Click in the play button in the editor at the top of your screen. Here you can see what the drill or story looks like in the desktop version as well as in the mobile version. Click on start to start the drill or story.

You can also preview individual questions. Click on the play button top right of the question you want to preview, see the image below. 

Within a story you can preview pages. Click on the play button at the top right of the page to preview the individual pages.

Besides previewing a question, a drill or a story, it is also a good idea to go through your content via 'My repertoire'. By doing this, you can experience how the learner goes through the content that you have created and you may find things that you won't find when you only use the preview modus.
