It would be great if videos/audio content introduce the topic before written content. It helps with understanding it better. I know that Nexford has actually worked on this via the weekly summary given of the first day of each module. However, if they can come during the preview, that would be great.

Also, having more video and audio content and possibly a feature in the classroom that reads out text at the click of a button would be great. Sometimes, I get stuck trying to understand a particular concept particularly with the external resources because it is wordy.
