Write a real answer. It is graded against the question's stored rubric, the mastery movement is computed by the same engine the product uses, and — the part worth watching — the next question is chosen by the real scheduler from what you have already answered. Nothing is saved and no tokens are spent.

You power a brand-new board for the first time and current draw immediately hits the supply's limit. Walk me through how you would debug it.
