I think you should complete Orientation at a medical school before even LOOKING at Step 1 resources. 😉 ~99% of my class didn't even look at any of that stuff before we received our M2 promotion letters. As for quality, FC sounds useless and DIT... I wasn't impressed with the videos I watched of theirs. First Aid, Pathoma, BRS Physio, Pharm Cards, UWorld, Rx, and a bunch of other supplementary books....
