The book is divided into plus a solutions appendix . Each chapter follows: theory capsule → worked examples → exercise sets (graded: Warming Up, Training Camp, IMO Arena) .
The PDF’s subtitle, “Bridging Gaps Between Training and Mastery,” hints at its core mission. It assumes the reader has already solved at least 50–100 standard olympiad problems. Now, it forces the reader to:
Most olympiad series follow a linear, topic-by-topic structure (Algebra → Combinatorics → Number Theory → Geometry). However, of the Second Step series breaks the mold. It is not for beginners (Volume 1–3) nor for IMO medalists (Volume 8–10). Instead, Volume 7 targets the transitional student—one who knows the theorems but struggles to apply them in novel combinations.
