Hang in there, I am so sorry for what you are going through, but I believe in your ability to pass next time! How representative was your Rosh predicted score? I also only did Rosh plus about 1/4 of the questions I got wrong. The Rosh projected score was 3 under my actual, and my R3 ITE was 2 under my actual. That said, I did not walk away feeling good about the exam, although I ended up passing comfortably. I felt like the format of the real deal was much different than Rosh which surprised me. I also had access to Hippo and Peer but did not use them. My friends said that Peer felt more representative of the actual ABEM test question style.
If I was in your situation I would take advantage of the time you have to solidify your knowledge base via hippo or other reading which will help with some of the trivia questions, re-do Rosh over summer/early fall, and I would also do PEER closer to the real thing. Being that you were soooo close, I would also consider the non-academic factors that could squeeze out a few more points too, like simulating the test length at home. I don't know about you, but my stamina wore out in the second half and I am sure I missed a couple as a result. Best of luck to you!
