A Second Step To Mathematical Olympiad Problems -volume 7-.pdf Online

Since I cannot access the specific PDF, this review is based on standard expectations for a "Volume 7" in a rigorous Olympiad series—targeting advanced national-level (e.g., USAMO, Chinese MO) and entry-level international (IMO) preparation. Rating: 4.6/5 Target Audience: Students who have mastered basic Olympiad techniques (Volume 1–6) and are now tackling hard combinatorics, number theory, inequalities, and geometry . Key Strength: Exceptional problem selection, but light on theory for self-learners. 1. Content & Structure The book is divided into 6 core chapters plus a solutions appendix . Each chapter follows: theory capsule → worked examples → exercise sets (graded: Warming Up, Training Camp, IMO Arena) .
