Why These Four Deserve Priority Revision

Because Family Medicine overlaps conceptually with the other specialty areas, it's easy to assume revising it covers Cardiology, Neurology and Endocrinology too — in practice the DHA tests each as its own domain, with its own classic signs and triads.

HighYield's DHA question bank covers all four of these specialties plus Infectious Diseases, Dermatology, Nephrology and every other discipline on the exam, with every question explained.
