Many professors post "Selected Solutions" or "Practice Problem Keys" on their public course pages.
Can you draw a graph without edges crossing? How many colors do you need so no two adjacent vertices share a color? These chapters involve complex proofs where seeing a worked-out solution can clarify the "Four Color Theorem" applications.
