For posterity, did the GW questions- passed comfortably. My fellowship prepared me well as we have multiple sites with different focus ( University for the Transplant & Cardiac stuff, VA for general stuff and a county hospital which sees tropical diseases and advanced HIV). I felt the ABIM syllabus was wayy off and probably close to 30-40% of the exam could have been classified as trop med questions.
Edit: I also took the board review course at ID week in my FL-2 year and went through my old First Aid for USMLE Step 1 to refresh all the stupid buzzwords (man I have never seen a staph saprophyticus UTI, they LIED to us lol )
