Query: Student test book to be used with class room instruction

This is not a stand alone book. It has chapters to go alongwith some text book and only contains questions and multi choiceanswers. It has no instructional benefit. It could be used as a testbook for a class room or something but not a good choice for someone wanting to learn about machining unless one had the text book that goes with it.
