Hi rtod46785,
Thank you for the great question! I am glad you asked
This WorBank is actually one of our most popular Premium features (also available during the 7-Day Free Trial of the site). I shot a quick video showing how you can add words from lessons to your personalized MyWord Bank so that you can see them from one location and review them using the Flashcard. Here's the link to the video:
