Use a tool like Excalidraw or a physical whiteboard to replicate the diagrams from the PDF from memory. This forces you to recall not just the components but their logical arrangement and interaction. Then, record yourself explaining your design. When you play it back, you'll be able to identify areas where your explanation is unclear or where you're missing key details. This level of active practice is what transforms passive knowledge from a PDF into a confident, executable skill.
