UNICAMP is usually ranked as the second best University in Latin America and the first on software development. My Associate (Undergrad) Degree in Systems Analysis and Development at the Technology College of UNICAMP, where we covered everything from the basics of computers and operating systems to more specific content related to system development. The course has a strong practical emphasis in areas such as analysis, engineering, software development, and architecture, where we studied various paradigms, patterns, databases, etc. Additionally, we were introduced to a mathematical foundation for computing through subjects such as Calculus, Discrete Mathematics, Linear Algebra, and Statistics.
