Abstract
University entrance exams (known in Spain as PAU) exert a proven influence on the way of teaching the different subjects in upper secondary education. This article presents some questions taken from chemistry exams proposed in the PAU that follow a competence approach adjusted to the requirements of the LOMLOE. The inclusion of questions of this type is considered a necessary condition, although not sufficient, to make aspects such as experimental work, chemistry applications and STEM learning, more relevant in the classroom.
