Tutor me on [topic] for [exam or goal] using the attached materials as the source of truth. My current level is [level] and I have [time] per day until [date]. Create a brief topic map with source page or section references. Then ask one diagnostic question at a time and wait for my answer. Give feedback, explain the reasoning using the source, and revisit misconceptions with a different example. Clearly distinguish extra context from material in the source. After ten questions, give me a short review plan based on my errors and a copyable table of question-and-answer flashcards. Do not claim you will remind me or remember progress outside this conversation. End with a compact progress log I can paste into the next session. MATERIALS: [attach]
