May want to clarify what UFAP/S stands for, since it's become so colloquial on this board that I don't think I've ever seen what it stands for written out, anywhere. Actually, you distinguishing between UFAP vs UFAPS only if Micro is weak is what finally made me click on what 'UFAP' stood for, if only because the components are so often referenced on here. For the first many months of browsing Allo, I just thought UFAP was a semi-derogatory way of saying "do UWorld until you can't do it anymore."
Fair point, and sorry busy as a resident, and just talk in abbreviated fashion now lol.
UFAPS = USMLE World + First Aid + Pathoma + SketchyMicro
Personally I don't think it matters what order you do it in, or how you get through those resources, or even if you have a weak foundation in any area to start with. What matters is getting through and learning the material in those resources as best as you can. Lean heavily on UWorld, including reading and understanding all the explanations for right and wrong answers.
At the bare minimum, I'd say just FA + UWorld, and I know people who only used those two resources and scored 230 at least or higher (which I know is low for SDN but fine for most, unless aiming for a very competitive specialty).
Good luck, OP!
