Open any question below and you get the paper back exactly as you left it - your highlights, your notes, what you crossed out - with a timeline of everything you did and when you did it. A score tells you how many you got. This tells you why.

By topic

Every question with your answer, what you eliminated, and the explanation.

Where the misses clustered

Read the trap column before the topic column - several misses sharing a trap are one habit, not several weaknesses.

Every miss

What you put, what was right, and why.

Full report

A Markdown file with every question, your answers, the full annotation timeline, and instructions telling an AI exactly how to analyse it. The one-press hand-off to a model is on the Summary tab.
