Older files in some versions of this archive may occasionally include solutions in the original host country’s language (e.g., Romanian, Bulgarian, or Serbian), though English is the official standard.

Euclidean geometry problems that require a deep knowledge of cyclic quadrilaterals, power of a point, and advanced triangle centers. jbmo.rar

The jbmo.rar file is a staple for young mathematicians. It usually includes a curated collection of past shortlists, longlists, and official competition problems spanning several years. The primary goal of this archive is to provide students with a clear understanding of the difficulty level and the "flavor" of problems encountered at the JBMO level. Key Content Areas Older files in some versions of this archive

Covers pigeonhole principle, counting strategies, and basic graph theory. Strengths It usually includes a curated collection of past

For any student or coach targeting the Junior Balkan Mathematical Olympiad, this archive is an essential resource . It offers the specific type of "middle-ground" challenge—harder than AMC 10 but more accessible than the IMO—that is necessary for developing advanced problem-solving skills.

Most archives include detailed proofs rather than just final answers, which is crucial for learning the "language" of mathematical proofs.
