Can I learn anything from this rock?

The photo's aren't detailed enough to get much info out of them. The rock looks like it has layers which may mean it's sedimentary. It also looks rounded like it's been rolled around a lot (common for beach rocks).

If you could provide clearer photo's with something in the picture for perspective it might help. Also if you could say something about the rock like what it's texture it like, that might help a bit too.

What beach did you find it on?

Here are better pictures, it's about the size on a tennis ball. The middle layer is more porous and the colours are grey, black, light grey, white, back to grey. There are some shells in it as well. I found it on Folly Beach, SC.

Ok. Fossils are pretty common in the Baltimore and Virginia shore area. So I think what you have there is a chunk of sedimentary rock containing a fossil layer which probably broke off north of where you found it, and was washed around in the ocean until it found it's way down to SC.
