Satan from the 7th Grade (Polish: Szatan z siódmej klasy) is a 1937 children's book (or rather, a young adult book - a term which did not exist at the time of writing) by Polish writer Kornel Makuszyński. It is considered a classic in Poland, where it has remained in print for decades, whatever changes and upheavals the country passed through. It is also popular in other countries such as Israel, where two Hebrew translations were published - the translators making a considerable effort to translate the colloquial Polish of the original into up-to-date Israeli equivalents. Note: The "Seventh Grade" of the title is according to the Polish educational system at the time of writing, where youngsters underwent four years of Elementary education followed by eight years of Further or High School. The book's protagonist is in the 7th grade of the latter, (11th grade in North American English-language usage) and is thus about 17 years old. Source: Wikipedia (en)
