A standard text for the teaching of Polish, this revised edition introduces two new features: a grammatical sketch of Polish and an index. Volume Two contains drills for the lessons in Volume One designed specifically for classroom instruction, a survey of Polish grammar, and an index to both volumes.
This is the best book I know of for thoroughly drilling Polish. That said, the dated vocabulary is somewhat irritating (e.g., enthusiastic use of the Polish word for "ashtray").
