        This is a diagnostic, not a review — it won't tell you how to fix the gaps.

        Now you know how well your draft answers the prompt.

        Now see what the reader is receiving from the whole essay — what lands, what they’ll remember, and the one thing worth changing first. Your first full Margin feedback pass is free.
