Fiocruz Launches Over 8,000 Free Online Health and Science Courses as CNU 2025 Exam Corrections Begin

The Oswaldo Cruz Foundation (Fiocruz) is providing a significant opportunity for health and science professionals and students with more than 8,000 free online courses available this October. These courses cover a broad spectrum of areas such as digital health, chronic disease care, aging, racial equity, and the One Health approach, responding to current public policy challenges. Registration is managed through Fiocruz's Acesso Único system, facilitating centralized access to the Virtual Campus where courses are offered. Most courses are self-paced, with certification issued within five business days upon passing evaluations, and educational materials remain accessible even after course completion.

Simultaneously, candidates for the CNU (National University Contest) 2025 Block 3, which includes vacancies in Sciences, Data, and Technology, can access unofficial answer keys provided by GLOBO to evaluate their exam performance. The exam, composed of an objective general knowledge test with 30 questions and a specific 60-question test divided into thematic axes such as Science, Technology, and Society, was held recently. Official test booklets and definitive answer keys will be released on October 6, 2025.

These developments underline the availability of educational and professional advancement opportunities in health, science, and technology fields, combining newly accessible public health training with transparency in competitive examinations.
