About
This is a path for those of you who want to complete the Data Science undergraduate curriculum on your own time, for free, with courses from the best universities in the World.
In our curriculum, we give preference to MOOC (Massive Open Online Course) style courses because these courses were created with our style of learning in mind.
Curricular Guideline
OSSU Data Science uses the report Curriculum Guidelines for Undergraduate Programs in Data Science as our guide for course recommendation.
How to use this guide
Duration
It is possible to finish within about 2 years if you plan carefully and devote roughly 20 hours/week to your studies. Learners can use this spreadsheet to estimate their end date. Make a copy and input your start date and expected hours per week in the Timeline sheet. As you work through courses you can enter your actual course completion dates in the Curriculum Data sheet and get updated completion estimates.
Warning: While the spreadsheet is a useful tool to estimate the time you need to complete this curriculum, it may not be up-to-date with the curriculum. Use the spreadsheet just to estimate the time you need. Use the the GitHub repo to see what courses to do.
Order of the classes
Some courses can be taken in parallel, while others must be taken sequentially. All of the courses within a topic should be taken in the order listed in the curriculum. The graph below demonstrates how topics should be ordered.
Track your progress
Fork the GitHub repo into your own GitHub account and put ✅ next to the stuff you’ve completed as you complete it. This can serve as your kanban board and will be faster to implement than any other solution (giving you time to spend on the courses).
Which programming languages should I use?
Python and R are heavily used in Data Science community and our courses teach you both. Remember, the important thing for each course is to internalize the core concepts and to be able to use them with whatever tool (programming language) that you wish.
Content Policy
You must share only files that you are allowed. Do NOT disrespect the code of conduct that you sign in the beginning of your courses.
Community
We have a Discord server! This should be your first stop to talk with other OSSU students. Why don’t you introduce yourself right now?
You can also interact through GitHub issues.

Warning: There are a few third-party/deprecated/outdated material that you might find when searching for OSSU. We recommend you to ignore them, and only use the OSSU Data Science Github Repo. Some known outdated materials are:
- An unmaintained and deprecated trello board
- Third-party notion templates
Prerequisites
The Data Science curriculum assumes the student has taken high school math and statistics.
Curriculum
- Introduction to Data Science
- Introduction to Computer Science
- Data Structures and Algorithms
- Databases
- Single Variable Calculus
- Linear Algebra
- Multivariable Calculus
- Statistics & Probability
- Data Science Tools & Methods
- Machine Learning/Data Mining
- Final project
Introduction to Data Science
Introduction to Computer Science
Students who already know basic programming in any language can skip this first course
Introduction to Computer Science and Programming Using Python
Introduction to Computational Thinking and Data Science
Data Structures and Algorithms
The Algorithms courses are taught in Java. If students need to learn Java, they should take this course first
Algorithms I: ArrayLists, LinkedLists, Stacks and Queues
Algorithms II: Binary Trees, Heaps, SkipLists and HashMaps
Algorithms III: AVL and 2-4 Trees, Divide and Conquer Algorithms
Algorithms IV: Pattern Matching, Dijkstra’s, MST, and Dynamic Programming Algorithms
Databases
Database Management Essentials
Data Warehouse Concepts, Design, and Data Integration
Relational Database Support for Data Warehouses
Business Intelligence Concepts, Tools, and Applications
Design and Build a Data Warehouse for Business Intelligence Implementation
MongoDB for Developers Learning Path
Single Variable Calculus
Calculus 1C: Coordinate Systems & Infinite Series
Linear Algebra
Multivariable Calculus
Statistics & Probability
Intro to Descriptive Statistics
Intro to Inferential Statistics
Statistical Learning with Python by Stanford University on EdX (Textbook, Textbook resources) or Statistical Learning With R by Stanford University on EdX (Textbook, Textbook resources)
Data Science Tools & Methods
Machine Learning/Data Mining
Supervised Machine Learning: Regression and Classification
Unsupervised Learning, Recommenders, Reinforcement Learning
Final project
Part of learning is doing. The assignments and exams for each course are to prepare you to use your knowledge to solve real-world problems.
After you’ve completed the curriculum, you should identify a problem that you can solve using the knowledge you’ve acquired. You can create something entirely new, or you can improve some tool/program that you use and wish were better.
Students who would like more guidance in creating a project may choose to use a series of project oriented courses. A sample of options (many more are available, at this point you should be capable of identifying a series that is interesting and relevant to you) are available on this page.
Congratulations
After completing the requirements of the curriculum above, you will have completed the equivalent of a full bachelor’s degree in Data Science. Congratulations!
What is next for you? The possibilities are boundless and overlapping:
- Look for a job as a data scientist!
- Check out the readings for classic books you can read that will sharpen your skills and expand your knowledge.
- Join a local data science meetup (e.g. via meetup.com).
- Pay attention to emerging technologies in the world of data science.
How to contribute
You can open an issue and give us your suggestions as to how we can improve this guide, or what we can do to improve the learning experience.
You can also fork this project and send a pull request to fix any mistakes that you have found.
If you want to suggest a new resource, send a pull request adding such resource to the extras section. The extras section is a place where all of us will be able to submit interesting additional articles, books, courses and specializations.
