The general resources include:
First Aid (tells you what you need to know for the STEP, but doesn't explain it) and Pathoma (explains pathology)
Uworld as a question bank.
Depending on knowledge base you may need to supplement with other resources. There are resources that try to cover every subject (DIT, Kaplan, etc), but I don't find them that helpful. I am making a full video course on Youtube (free), so message me if you'd like to check that out.
