"We've been getting a lot of questions ever since our GMAT Choose Your Own Adventure video went up. Well, one question, really: How can I make one for my students?
Answer: It's easy! Youtube has a great tool called Spotlight that lets you make any video interactive. It's really handy for lessons and quizzes. Essentially, you can ask students a question - or a series of questions - and when they answer show them a personalized video response according to how they did."
