Here is a brief overview and a sample problem that captures the spirit of the competition. The Spirit of the VMO Selected Problems of the Vietnamese Mathematica...

The Vietnamese Mathematical Olympiad (VMO) is legendary in the competitive math world for its grueling multi-day format and its penchant for "beautifully difficult" geometry and functional equations. Proving bounds or convergence in sequences

At first glance, the sequence grows very slowly because we are adding small fractions. However, as stays within a range , we are repeatedly adding as stays within a range

Deep dives into roots and coefficients that require more than just Vieta’s formulas.
