I was skeptical at first, but it ended up being by far the best resource (even much better than Pathoma in my opinion). With that being said, I'm of the personal opinion that boards are slowly moving away from questions that can be easily answered by SketchyMicro so you will definitely still need to know the ins and outs of the First Aid microbiology portion. I also thought SketchyPharm was worth it and covered everything on both my board exams, but SketchyPath had only just come out when I hit dedicated so I didn't spend time on it, but have heard that is great as well. I will also say I haven't watched any of the videos for several months and they sill have have helped out enormously during rotations thus far.
