Agreed that Goljan's audios are awesome. Just be mindful that they're a wooden tennis racquet and some of his info is outdated. Eg, he had said lung beat colon for metastasis to liver. But it's always colon. And he stressed Casal necklace for B3 deficiency. But hyperpigmentation of the forearms is exceedingly HY for pellaga on Step 1 (ie, you don't want to be like 'well it's not on the neck so it can't be pellagra; point is sun-exposed areas, period). Just two things off the top of my head. Can't comment on Pathoma audio though.
