• Start with the rubric and ask AI to convert it into a checklist.
• Create a thesis before drafting the full assignment.
• Use one paragraph for one main idea.
• Ask AI to identify weak arguments and missing evidence.
• Use citation tools from the beginning, not at the end.
• Read your final draft aloud to catch flow issues.
• Keep a separate source log for every assignment.
