This template allows you to build your class schedule, as a student or as a teacher (teaching schedule). All you need to enter per class is [name], [its day of the week] , [time it starts], [how long it is], [a color] and [a class link]. Finally enter the time your earliest class starts and the template does the rest. All colors are adjustable. It is really simple and elegant.
