About Chile Competitive Exams
Chile's university admission system underwent a major transformation with the introduction of PAES (Prueba de Acceso a la Educación Superior) in 2022, replacing the former PSU. PAES emphasises reading competency and mathematical reasoning in real-world contexts rather than content memorisation. SIMCE (Sistema de Medición de la Calidad de la Educación) assesses school-level educational quality across primary and secondary grades. PAES Ciencias is the elective sciences component essential for admission to health, science, and engineering programmes at Chile's universities. Chile has a mixed higher education system with both prestigious public universities (Universidad de Chile, Universidad de Concepción) and strong private universities (Pontificia Universidad Católica de Chile, Universidad Adolfo Ibáñez). The CRUCH (Consejo de Rectores de las Universidades Chilenas) coordinates university admissions using a weighted formula of PAES scores, GPA (NEM), and class rank (ranking). DEMRE (part of Universidad de Chile) designs and administers all PAES tests.
How to Use These Mock Tests Effectively
- 1PAES Lectura rewards critical reading — practice analysing argument structure, identifying the author's stance, and evaluating the quality of reasoning in complex texts.
- 2For PAES Ciencias, focus on Biology (genetics, ecology), Chemistry (stoichiometry, acids/bases), and Physics (kinematics, electricity) — these are consistently the highest-yield topics.
- 3DEMRE publishes official ensayos (practice tests) — practise with these under timed conditions to experience the actual format.
- 4Your NEM (GPA) and class ranking both count toward university admission — consistent academic performance during school matters as much as the PAES score.
