Start with one topic
Do not paste an entire course at once. Pick one lecture, one chapter, or one past-paper topic. Smaller inputs make more precise cards.
Write cards as questions
Good cards ask one thing at a time. Instead of saving a paragraph, turn it into a question like: What is the difference between fixed cost and variable cost?
Mix definitions with examples
Definitions help you remember terms. Examples help you apply them. A strong deck should include both.
Review and remove weak cards
After generating cards, delete duplicates, vague questions, and anything you would never revise. Quality matters more than volume.
