Hi - the raw scores are just that - the number of correct answers out of 100. Then the composite is scaled. Some words of advice - study H&N a ton, hardly study gross - there were maybe 5 or so gross questions on mine, or so it seemed. Don't skimp on histology, once again focus on head and neck. Know your physiology concepts, I recommend the BRS review books, they have really good synopsis and review questions. Study da/occlusion a lot - I think some people forget it's 1/4th of the test and if you do really well it couldl bring up your overall score quite a bit. Just know the basic names/enzymes etc for the cycles and principles behind biochem - it really was way less detailed than I expected it to be. And study micro as much as possible because that was the area I felt worst about even though I did study. Don't rely too much on decks, although they are a good supplement. I used mainly notes from classes taught well and then BRS books for those that weren't - and I got a 90. Don't worry, you'll be fine - good luck!
