Checkpoint: Advanced Inputs and Outputs
A quick check on the extension lesson your class chose. Nothing here is new.

If you miss a question, take the checkpoint again. The goal is to get it right, not to get it right the first time.
Stuck? Go back to this lesson’s Learn module and to your worksheet — the answers are in both.
