🥵 HARD

This is one in a series of neuroanatomy “mid-term” papers designed to really test those looking to pursue careers in neurology, neurosurgery, psychiatry or those who have a particular interest in neuroscience and anatomy.  Recommended as part of Warwick Medical School’s NeuroSoc preparation for the National Undergradute Neuroanatomy Competition in Southampton, this can be a challenge for all!  Good Luck. 

The examination rules: 

  • This is a mock examination, and as such should be undertaken alone, in one attempt and under timed conditions. 
  • Please allow no more than 1 minute per question. 
  • A reasonable grading for someone with an interest in neuroanatomy would be:
    • <70% fail, 70% B, 80% A, 90% A*
