I just wrapped up CS50x and I'm looking for a meaningful next step rather than diving into another beginner's course. I'm considering MIT's 6.S081 (Operating Systems Engineering), but I have a few concerns I'd like to hear from people who've actually taken it, especially online through OCW. Here are my main questions:
- Can this course be realistically completed as a self-learner without being a student at MIT?
- How do the labs compare in difficulty to CS50's assignments?
- Do many people actually finish it independently, or do most tend to drop out?
- How crucial is it to have prior Unix/Linux experience?
- Will this course significantly enhance my software engineering fundamentals, or is it too advanced for where I am right now?
For context, my background includes:
- Completing CS50x
- Being comfortable with C at the CS50 level
- Limited experience with Unix/Linux
- A strong desire to deepen my understanding of computer science.
I really want to avoid getting stuck in beginner loops and merely collecting badges, but I also don't want to tackle something that's too ambitious for a solo learner like myself.

Check out the GitHub repo ossu/computer-science. Their core CS section is a great follow-up, especially since you're focused on building your foundational knowledge.
What’s your aim with this? Do you want to dive deep into computer science just for fun, or are you aiming for a career? Knowing that could help guide your choice better!
Honestly, think twice if you're getting into this field just now. The landscape's changing, and AI might create fewer job options for newcomers soon.

I’m still figuring out my exact long-term direction, but I want a solid foundation in computer science instead of remaining in the beginner zone. I’ve heard courses like 6.S081 really strengthen those fundamentals, so I’m considering if that’s the right move.
