Problem 3 (Geometry) was noted for its "attackability" through multiple different methods, including classic Euclidean geometry, vectors, and coordinate geometry.

Problem 1 was criticized for being perhaps too simple for an international olympiad, acting more as a "points booster" than a differentiator for top talent. Comentarii JBMO 2015

. Commentary suggests this was a very accessible problem, possibly even at a 5th or 6th-grade level, which resulted in a high number of maximum scores. Problem 3 (Geometry) was noted for its "attackability"

This problem involved minimizing a specific expression given the constraint including classic Euclidean geometry
