U--->PG

1. Discriminatory language is allowed in a PG compared to a U but only with strict education or historical context
2. Violence can be slightly stronger bu still justified by context
3. More frightening sequences are allowed but still must not be prolonged
4. Sex references must still be infrequent and only natural nudity
5. There can be mild drug references in PG compared to  in U but they must contain a strong anti drug message
