Practice text for middle school entrance exam preparation to build your skills with actual entrance exam questions. This is a practice text for middle school entrance exams for mid-tier private schools to prestigious national and private middle schools. It primarily features carefully selected actual entrance exam questions. It comes with a comprehensive separate answer booklet. There is also an aptitude test edition for public combined junior-senior high school entrance exam preparation. We recommend using this in conjunction with Effort for difficult school preparation. After building your skills by practicing basic and standard level problems with Effort, it is more effective to use Serpass for full-scale entrance exam preparation and advanced level problem practice.
