I was testing earlier if my signature was still showing for some reason on some threads it doesn't. But to answer your question with a little more detail then BnD did.
1. Yeah I think passing was 180
2. It covers mostly the first 2 years of med school, but has been having a more clinical tilt to it lately.
3. If you go to school in the U.S. usually at the end of second year before you start 3rd year rotations.
4. Some studys have said that it correlates with the mcat, and other studys have said it correlates more with the verbal section. I don't know if any of that is true, because alot of people here with really good scores didn't do so hot on the mcat.
Hope that helps.
