With anytime, anywhere, any device access, participants can watch their 3 to 5 minute video classes on their phones, tablets or laptops, when and where it suits them. Maybe on a coffee break at work or while relaxing at home. They can choose English or Spanish, closed caption options, and can download and print transcripts. At the end of each class, Vdio tests their comprehension with a four-question quiz, and gives them real-time feedback. If they get one answer wrong, they are immediately given the right answer. If they miss two, they are prompted to watch the video again.
