The MSAR is the official, authoritative guide to all of the allopathic medical colleges in North America; it would be unwise to apply to medical school without using it as a guide. In the past it presented an overview of each school on a two-page spread complete with admissions statistics, selection criteria, pre-requisites, and curriculum information. The best part of the MSAR was this easy-to-navigate layout with quick access to all of the information needed to make application decisions. Apparently, that was too convenient and logical.
With the new MSAR, the AAMC has published 286 of the most useless pages ever written on the topic of medical college admissions, ranking them above forest fires in the list of tragedies befallen by trees. All of the important information and data is now accessible only through the MSAR website, where you will find it (maybe) buried under a frustrating mountain menus and sub-menus that have been optimized for inefficiency. You'd be forgiven for suspecting that AAMC employs an army of watchmakers and cryptographers whose sole task is to uncover new and exciting ways to obscure two pages' worth of information. That's the only logical explanation.
Hopefully, the website will be improved next year, and they will return the printed edition to its previous form. In the mean time, I would recommend purchasing last year's edition on amazon, despite the inflated price (probably caused by the swarm of people seeking refuge from the horrors of the new format).
Disclaimer: The content of this review rests on the assumption that the AAMC intends the 2012 MSAR to be used as an aid to medical college admissions. I would feel quite silly if they were actually trying to market an exotic firewood substitute, as the MSAR performs admirably in this respect.
