This is a 2024 edition national high school entrance exam math problem collection that my child, who was a student preparing for exams last year, received at cram school ☺︎ I checked inside and it appears to be unused, with no writing or markings ⭐︎ I apologize if I missed anything. It seems to contain thoroughly researched, noteworthy math problems that are organized ⭐︎ It also includes answers and explanations, as well as a separate booklet with calculations and single-line problems to improve your score ☺︎ Although it's from last year, how about using it to improve your score and for daily home study ☺︎? - Title: 2024 National High School Entrance Exam Problem Collection - Math - Year: 2024 - Contents: High school entrance exam problem collection - Subject: Math - Table of Contents: Problems from each chapter are organized - Included: Separate booklet with calculations and single-line problems
