All of physiology is high yield. Can't stress knowing the BRS Phys book backwards and forwards enough! I had countless questions on GI physiology, action of hormones, etc.
Neuroanatomy wise, know your blood vessels and how different areas of the brain correlate to pathology. Left sided stroke vs right sided stroke, where is brocas, wernickes, where is the defect in Huntington's, etc. Knowing all the different parts of the thalamus and obscure pathways and brain slices like red nucleus is overkill. Knowing where the CN originate is important but to id them on brain slices may or may not be necessary depending on the test you get.
Biochem- use UCV Biochem and then you're set
Anatomy- Brachial plexus and the arm nerves are the most high yield. Some CT reading required but VERY basic. Legs are less tested but again depends on the test you get.
