About OSSU Data Science
OSSU Data Science organizes online courses into a self-paced study path based on an undergraduate data science curriculum. It follows the Curriculum Guidelines for Undergraduate Programs in Data Science and favors MOOC-style courses, covering introductory programming and data science, data structures and algorithms, databases, calculus, linear algebra, statistics and probability, tools and methods, machine learning, and a final project.
It provides a topic-order graph, a spreadsheet for estimating completion time, and progress tracking by forking the GitHub repository. The curriculum assumes high school math and statistics, and notes completion in about 2 years with roughly 20 hours of study per week. Discussion is available through Discord and GitHub issues.
