After thinking about it more (and getting scores back) need to clarify my prior thoughts on rad bio to not freak people out for next year. It was not an unfair test overall. Actually, it really was on par with the physics exam as far as level of difficulty. Most of it is pretty straight forward and it shouldn't be hard to get 70% or more right. It was just a little surprising that rad bio was on par with physics as far as difficulty. Conventional wisdom has always been that the Astro Rad Bio Study guides are a harder version of the real thing. I don't know what it will be like next year but it didn't feel that way this year. But most of the test was stuff residents should know off the top of their heads, so its nothing to worry about. Some of us just vented surprise when the real thing didn't fit our expectations going into it.
As for physics, cause someone will ask, this year at least it felt just like taking a raphex exam. They were very representative of the real thing. Go over raphex, listen to Caggiano, and you will be fine. Good luck to everyone next year!
