If you want a computer science education that feels like a university program rather than a pile of unrelated tutorials, start with two resources: MIT OpenCourseWare for university-level lectures and exams, and OSSU Computer Science for a complete curriculum assembled from free courses. The roundup behind this guide, titled “Real university courses, lectures and full curricula, free,” groups 15 resources by what they give you: course material, course platforms, self-directed curricula, lecture indexes, and coding-interview practice. Those categories matter more than the list order, because they tell you what kind of study each resource supports.
Where to start
The two starting points are different in kind. MIT OpenCourseWare is a body of course material: lecture notes, videos, and exams from MIT courses. OSSU is a sequence: it tells you which free courses to take and in what order. A learner who wants to work through real university material on their own schedule can begin with OpenCourseWare. A learner who wants to be told what to study next can begin with OSSU, and use OpenCourseWare courses to go deeper where OSSU points them.

The 15 resources at a glance
The roundup lists the following. Where it gives no description, the table says so rather than filling the gap with a guess. Provider pages are the place to confirm current access.

Choose your path before you choose a resource
Most learners fail not from lack of material but from switching between formats without a plan. Decide first which of these goals applies to you:
#1 Best Overall
- Foundations and breadth. Choose a curriculum such as OSSU or Teach Yourself Computer Science, then fill gaps with university course material.
- Specific topics in depth. Use the lecture index (CS video courses) or a university course page to study one subject thoroughly.
- Job-interview preparation. Use NeetCode alongside, or after, your foundational study. It is practice rather than a course of study.
- Niche systems topics. The three creator-made resources (eBPF, macOS Kernel & System Extensions, and Nix) are narrower subjects. The roundup does not describe their content, so check their own pages before committing time.
Build a sequence instead of browsing
A large lecture index is useful once you know what you are looking for, but without a spine it encourages random sampling. A coherent curriculum gives you an order: each subject builds on the last, and you know what “done” looks like. Our suggested approach, which is editorial guidance drawn from how the roundup describes these resources:
- Pick one curriculum as your spine. OSSU or Teach Yourself Computer Science are the clearest choices.
- For each subject in that spine, pick one university course from MIT OpenCourseWare, Carnegie Mellon’s Open Learning Initiative, or the CS video courses index, and work through its lectures and exercises.
- Keep a single list of completed subjects so you can see gaps across the whole sequence.
- Add interview practice once you can explain core data structures and algorithms in your own words.
Compare options on the same axes
If you are comparing two or more resources, use the same questions for each:
- Curriculum coverage and sequence: which subjects are included, and do they build on each other?
- Exercises and assessment: are there problem sets, exams, or graded work, and how deep are they?
- Format and pacing: is it self-paced, or does it run on a fixed schedule?
- Prerequisites: what do you need to know before starting?
- Delivery: lectures, text, or interactive exercises?
- Goal: foundational study or interview preparation?
The roundup gives enough detail to make these axes useful, but not enough to score every current course on them. Score each course yourself when you open it.

What “free” covers
Free study is not the same as a free credential. MITx courses can be audited for free, but that does not guarantee that every track, certificate, or assessment is free. The roundup notes that Coursera certificates cost money. Before you commit to a course, check the provider’s current page for enrollment access, certificate pricing, and terms. Course versions and availability change, and this guide has not verified the live state of any listed course.
Optional: a book companion
Teach Yourself Computer Science pairs each of its nine subjects with one book and one lecture series. A book can be a useful reference alongside the lectures, but it is optional. You can complete the free course material without buying anything. The roundup does not name specific titles or editions, so choose a current book for each subject by checking its edition and publication date.

Pick a spine, choose one university course per subject, and use the interview practice once the fundamentals are in place. Check each provider’s current terms before you rely on any free offer.
