Potential gems on the list might be the OS or networking course if they are run something like MIT's 6.828 with lots of lab coding and perhaps a bit of hand-holding, but if you can just clone last semester's 6.828 repo and get osdev'ing, why drop 10k to spend most of your time on courses that look like yawn central?
I think what I really wanted to see was a lab-focused curriculum for aspiring vulnerability researchers, so perhaps I was bound to be disappointed.
