Cram school

A cram school (colloquially: crammer, test prep, tuition [center], or exam factory) is a specialized school that trains its students to achieve particular goals, most commonly to pass the entrance examinations of high schools or universities. The English name is derived from the slang term cramming, meaning to study a large amount of material in a short period of time. The word "crammer" may be used to refer to the school or to an individual teacher who assists a student in cramming.
