It has been most helpful in expanding my vocabulary. I truly believe that no other system can beat Advanced English in improving vocabulary. Even if a Longman dictionary were to be converted to SuperMemo format, it would not provide that simple and easily memorizable definitions. I have memorized 10,000 items in 18 months without a major effort and consider it a great success. No further comments.
