Leech

Leeches in SuperMemo are questions that a student keeps forgetting. Most often leeches come from disrespect for the 20 rules of knowledge formulation. Some well-formulated material may also need a boost from mnemonic techniques or a boost in coherence, e.g. by setting questions in relevant context.
