## What's a Short Course?White Crane Education's short courses are focused summaries of specific topics intended for students who need a quick review or a different perspective on a specific concept or technique. These classes also include our signature dynamic content that gives students the opportunity to work through a wide variety of sample problems. | ## Technologies UsedWe try to limit the technologies that are used in each classroom to the minimum required to get the job done. The combinatorics classroom uses only JavaScript which all modern browsers support. |
