Prerequisite for both is CS1-2. Either course (Berkeley and Carnegie Mellon) is suitable as an alternative to nand2tetris and/or 6.004 as the required course of choice for Computer Architecture/Organization. The Princeton course that's already here would have one of these 4 courses as a prerequisite and is suitable as an elective.
GTx CS1301, "Computing In Python" is proposed as a supplemental course in the OSSU curriculum and as a potential future candidate for the Introduction to Computer Science course. It is an online-adapted version of the on-campus Introduction to Computing course for Georgia Tech computer science students. The online version is comprised of four parts, delivered on-demand via edX. The course is self-paced with 16 weeks of effort, and is 100% free to audit with all materials included. It covers all introductory CS topics discussed in MIT 6.00.1x from a language-agnostic perspective, while providing additional instruction and support in learning Python as a language. Students who complete this course will have an understanding of basic CS topics **and** a working knowledge of Python 3 they can immediately apply to interesting problems.
Since we want every course in Intro CS and Core CS to be required, I have removed
the optional courses from Intro CS. But they are still good courses so I made
a new section in extras/courses.md to house courses on online learning.
I also added a new course under this new section, the sequel to Learning How
to Learn.
