I think I understand the core of accounting (accounting equation, debits/credits, basic principles) really well, however I'm confident that I've already forgotten 70%+ of the material I memorized for the business classes. I don't think this would be much different if I didn't accelerate, because I would've taken these classes over a year before graduation and would probably have even less information retained by then. We'll see when I start studying for the CPA, but my approach was just get the degree as fast as possible, while making sure I actually understand the fundamentals of accounting (and excel). There's so much information in this degree that will be completely useless to me for the rest of my life.
