It's a cumulative checkpoint meant to confirm several foundational concepts stuck together, mirroring how real projects require moving between different areas of the topic quickly.

What should I do if I get a question wrong?

Revisit the lesson covering that specific concept before moving on — each explanation points at exactly what to re-read.
