The simple answer is some students won’t need it as much as others. Those that do, however, really need it! Merely completing a two-dimensional or “basic” design class implies no degree of proficiency. Some people simply take longer than others when it comes to grasping notions of rhythm and unity. Remember, design elements are relatively tangible. It’s the more abstract notions of design principles that seem to be the vexing agent. Anyone can draw and identify a pair of shapes. Identifying how the shapes relate to each other and how that relationship can become even more interesting, that’s the wild card. Some grab on early, others don’t. Some simply require an alternate pathway.
