- All courses have units with videos, text and exercises.
- You will need a device with audio output such as a headphone or speakers to listen to the audio of the videos.
- Some videos have captions or subtitles (text of the audio). To view the captions/subtitles, start playing the video and then click on the button labelled “CC” (see image below).
- Most units have exercises, see example below. While some are quick to answer, others will require you to take time to reflect.
