I'm taking an abstract algebra course that uses Hungerford's "An Introduction to Abstract Algebra" 3rd Ed. And while I feel like I'm following the material sufficiently and can do most of the proofs it's hard to learn and practice the material without a solutions guide. How am I supposed to know the work I've practiced outside of class is correct, or if I have misunderstood a fundamental concept without a way to check my work? I understand that as I approach subjects that are intrinsically more difficult it will require more time to understand the concepts. I'm taking abstract and real analysis simultaneously, on top of physics and cs courses, so staring at a page for hours on end isn't really a viable solution. Whereas simply looking at the solution to the problem could show me the error in my understanding in a matter of minutes. That being said... is there a solutions manual / solutions anywhere? I've been scraping the web and have come up empty handed. I can't even find an instructor's solutions manual.
