Answer

If they're both graduates, you simply need to ask where the person graduated from. If the name of the institution doesn't give away what type of place it is, you can ask them to clarify.

I don't even know from the top of my head what a graduate school is.

Answer

People who have graduated from uni are called graduates. They then can take a post-graduate class. They would be post-graduates. I hope this helps :)
