“If you can design one thing, you can design everything.” - Massimo Vignelli
What caught my attention in this info graphic is the huge bolded "3". We can use this idea to separate each grades or classes. For elementary to middle school, we can emphasize the grade in big bolded black numbers(1~8) and the classes in a grey(50% capacity)(A~D) so that we can put text over it. For high school, we dont have "classes" so just the numbers.
