Reference excerpt

The University Selection Test (Spanish: Prueba de Selección Universitaria or PSU) was a standardized test used for college admissions in Chile, made by the Department of Evaluation, Measurement and Educational Register (Departamento de Evaluación, Medición y Registro Educacional or DEMRE) by mandate of the Board of Chilean Universities' Headmasters (Consejo de Rectores de las Universidades Chilenas, or CRUCH). Since 2003, it had replaced the Prueba de Aptitud Académica (PAA) which had been in use since 1966, until its eventual termination in 2020. A temporary test (Prueba de Transición) was used while the Prueba de Admisión a la Educación Superior (PAES) was in development. The PSU was given once a year, usually between November and December. It was necessary to take the test to apply to universities ascribed to the CRUCH, known as Traditional Universities. The only requirement to take this test was to have completed high school.

Format The PSU itself was a set of four separate tests, which were taken in two days. Out of these four:

Two were required (Reading Comprehension and Mathematics) Two were optional, yet it was required to choose one History and Social Studies Science: This test had a common module of Biology, Physics and Chemistry (referring to the curriculum of the first two years of secondary education) and three elective modules from which one is chosen (Biology, Physics or Chemistry - referring to the curriculum of the 3rd and 4th years of secondary education) The maximum score was of 850 points, and the minimum, 150 points.

Worked examples

Example 1 — a first encounter with Prueba de Selección Universitaria

Start with the simplest possible case. Write down what Prueba de Selección Universitaria claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Prueba de Selección Universitaria before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Prueba de Selección Universitaria ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Prueba de Selección Universitaria

In research: Prueba de Selección Universitaria appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Prueba de Selección Universitaria in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Prueba de Selección Universitaria is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chile stubs, Education in Chile, South America education stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Prueba de Selección Universitaria outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
