Summary
The OSSU curriculum is a complete education in computer science using online materials. It’s not merely for career training or professional development. It’s for those who want a proper, wellrounded grounding in concepts fundamental to all computing disciplines, and for those who have the discipline, will, and (most importantly!) good habits to obtain this education largely on their own, but with support from a worldwide community of fellow learners.
It is designed according to the degree requirements of undergraduate computer science majors, minus general education (nonCS) requirements, as it is assumed most of the people following this curriculum are already educated outside the field of CS. The courses themselves are among the very best in the world, often coming from Harvard, Princeton, MIT, etc., but specifically chosen to meet the following criteria.
Courses must:
 Be open for enrollment
 Run regularly (ideally in selfpaced format, otherwise running at least once a month or so)
 Fulfill the academic requirements of OSSU
 Fit neatly into the progression of the curriculum with respect to topics and difficulty level
 Be of generally high quality in teaching materials and pedagogical principles
When no course meets the above criteria, the coursework is supplemented with a book. When there are courses or books that don’t fit into the curriculum but are otherwise of high quality, they belong in extras/courses or extras/readings .
Organization. The curriculum is designed as follows:
 Intro CS : for students to try out CS and see if it’s right for them
 Core CS : corresponds roughly to the first three years of a computer science curriculum, taking classes that all majors would be required to take
 Advanced CS : corresponds roughly to the final year of a computer science curriculum, taking electives according to the student’s interests
 Final Project : a project for students to validate, consolidate, and display their knowledge, to be evaluated by their peers worldwide
 Pro CS : graduatelevel specializations students can elect to take after completing the above curriculum if they want to maximize their chances of getting a good job
Duration. It is possible to finish Core CS within about 2 years if you plan carefully and devote roughly 1822 hours/week to your studies. Courses in Core CS should be taken linearly if possible, but since a perfectly linear progression is rarely possible, each class’s prerequisites is specified so that you can design a logical but nonlinear progression based on the class schedules and your own life plans.
Cost. All or nearly all course material prior to Pro CS is available for free, however some courses may charge money for assignments/tests/projects to be graded. Note that Coursera offers financial aid . Decide how much or how little to spend based on your own time and budget; just remember that you can’t purchase success!
Content policy. If you plan on showing off some of your coursework publicly, you must share only files that you are allowed to. Do NOT disrespect the code of conduct that you signed in the beginning of each course!

Prerequisites
 Core CSassumes the student has already taken high school math and physics, including algebra, geometry, and precalculus. Some high school graduates will have already taken AP Calculus, but this is usually only about 3/4 of a college calculus class, so the calculus courses in the curriculum are still recommended.
 Advanced CSassumes the student has already taken the entirety of Core CS and is knowledgeable enough now to decide which electives to take.
 Note thatAdvanced systemsassumes the student has taken a basic physics course (e.g. AP Physics in high school).

Advanced CS
After completing every required course in Core CS, students should choose a subset of courses from Advanced CS based on interest. Not every course from a subcategory needs to be taken. But students should take every course that is relevant to the field they intend to go into.
The Advanced CS study should then end with one of the Specializations underAdvanced applications. A Specialization’s Capstone, if taken, may act as theFinal project, if permitted by the Honor Code of the course. If not, or if a student chooses not to take the Capstone, then a separate Final project will need to be done to complete this curriculum.

These Coursera Specializations all end with a Capstone project. Depending on the course, you may be able to utilize the Capstone as your Final Project for this Computer Science curriculum. Note that doing a Specialization with the Capstone at the end always costs money. So if you don’t wish to spend money or use the Capstone as your Final, it may be possible to take the courses in the Specialization for free by manually searching for them, but not all allow this.

Final project
OSS University is projectfocused . You are encouraged to do the assignments and exams for each course, but what really matters is whether you can use your knowledge to solve a real world problem.
After you’ve gotten through all of Core CS and the parts of Advanced CS relevant to you, you should think about a problem that you can solve using the knowledge you’ve acquired. Not only does real project work look great on a resume, the project will validate and consolidate your knowledge. You can create something entirely new, or you can find an existing project that needs help via websites like CodeTriage or First Timers Only .
Another option is using the Capstone project from taking one of the Specializations inAdvanced applications; whether or not this makes sense depends on the course, the project, and whether or not the course’s Honor Code permits you to display your work publicly. In some cases, it may not be permitted; do not violate your course’s Honor Code!

Evaluation
Upon completing your final project, submit your project’s information to PROJECTS via a pull request and use ourcommunitychannels to announce it to your fellow students.
Your peers and mentors from OSSU will then informally evaluate your project. You will not be “graded” in the traditional sense — everyone has their own measurements for what they consider a success. The purpose of the evaluation is to act as your first announcement to the world that you are a computer scientist, and to get experience listening to feedback — both positive and negative — and taking it in stride.
The final project evaluation has a second purpose: to evaluate whether OSSU, through its community and curriculum, is successful in its mission to guide independent learners in obtaining a worldclass computer science education.
Cooperative work
You can create this project alone or with other students! We love cooperative work ! Use ourchannelsto communicate with other fellows to combine and create new projects!
Which programming languages should I use?
My friend, here is the best part of liberty! You can use any language that you want to complete the final project.
The important thing is to internalize the core concepts and to be able to use them with whatever tool (programming language) that you wish.
Pro CS
After completing the requirements of the curriculum above, you will have completed the equivalent of a full bachelor’s degree in Computer Science, or quite close to one. You can stop in the Advanced CS section, but the next step to completing your studies is to develop skills and knowledge in a specific domain. Many of these courses are graduatelevel.
Choose one or more of the following specializations :
 Mastering Software Development in R Specialization by Johns Hopkins University
 Artificial Intelligence Engineer Nanodegree by IBM, Amazon, and Didi
 Machine Learning Engineer Nanodegree by kaggle
 Cybersecurity MicroMasters by the Rochester Institute of Technology
 Android Developer Nanodegree by Google
These aren’t the only specializations you can choose. Check the following websites for more options :
 edX: xSeries
 Coursera: Specializations
 Udacity: Nanodegree
Where to go next?
 Look for a job as a developer!
 Check out the readings for classic books you can read that will sharpen your skills and expand your knowledge.
 Join a local developer meetup (e.g. via meetup.com ).
 Pay attention to emerging technologies in the world of software development:
 Explore the actor model through Elixir , a new functional programming language for the web based on the battletested Erlang Virtual Machine!
 Explore borrowing and lifetimes through Rust , a systems language which achieves memory and threadsafety without a garbage collector!
 Explore dependent type systems through Idris , a new Haskellinspired language with unprecedented support for typedriven development.

 Copy this board to your personal account. See how to copy a board here .
Now that you have a copy of our official board, you just need to pass the cards to the Doing
column or Done
column as you progress in your study.
We also have labels to help you have more control through the process. The meaning of each of these labels is:

Main Curriculum
: cards with that label represent courses that are listed in our curriculum. 
Extra Resources
: cards with that label represent courses that was added by the student. 
Doing
: cards with that label represent courses the student is current doing. 
Done
: cards with that label represent courses finished by the student. Those cards should also have the link for at least one project/article built with the knowledge acquired in such course. 
Section
: cards with that label represent the section that we have in our curriculum. Those cards with theSection
label are only to help the organization of the Done column. You should put the Course’s cards below its respective Section’s card .
The intention of this board is to provide our students a way to track their progress, and also the ability to show their progress through a public page for friends, family, employers, etc. You can change the status of your board to be public or private .
