When browsing the course catalog, you can easily bookmark a course to review again later. Find a course you'd like to bookmark, hover your mouse over that course and click "Preview Course".
You'll then see the pop-up preview window and at the bottom right of the pop-up click "Bookmark".
To review the courses you've bookmarked, navigate back to your Dashboard screen by clicking the "MedBridge" icon in the top left corner of the webpage, then go to Courses > Bookmarked.
