I feel like I missed a few things in school, database theory, queuing, optimizing IR in a compiler, etc.<p>Is there a cost efficient way to take these undergrad/grad CS courses at a college after completing your degree?<p>I do prefer a formal course with an instructor but, if those are going to be very expensive, do you have suggestions for alternative resources?
I would recommend coursera: <a href="https://www.coursera.org/browse/computer-science/software-development" rel="nofollow">https://www.coursera.org/browse/computer-science/software-de...</a>.
