Hit a wall

[jb111]

Hi all.  I made the mistake of starting a new job and MBA at the same time.  I knew it was a risk but went forward anyway.  The job turned out to be much bigger than expected.  At this point I'm trying to decide what to do.  The school only has $375 and will extend the 1st class (very generous).  I will finish it but may not continue (for a while).  I really want to learn the MBA material but don't "Need" the degree.  Has anyone done self-study in this area?  I'd like to review what I can until the job relaxes (or I find another one).  So far I have a couple books and a Udemy course.  I wish we a Study.com-like program.  I love the learning style.  Thank you
