Upcoming inservice... what other review books/question books?

Peer is purchase through ACEP's bookstore.
If you can get your hand on a copy of Rivers review books, they aren't bad. Outline form, quick read. Can't buy it anymore, though, as they stopped making it.
This question book isn't bad, either.

Not that this will get you ready for the inservice, but it just helps refresh info in general... ACEP is offering a free spaceded (that's spaced education) course I think of Peer VII Q's. The idea is you learn better with few questions repeated over a longer period of time than in short bursts. They send you two or three questions daily.

Its been helpful for me. Find it here: http://acep.spaceded.com/

incidentally, some of the spaceded courses for medstudents are still helpful as a resident, eg. ACLS, cardiology etc.
