TJHSST BRAIN BEE PRACTICE TEST #1
Archis R. Bhandarkar
This practice test is meant to simulate questions that will be asked of Brain Bee competitors participating in the Phase II or Oral Round of the competition. All questions are taken from the Society of Neuroscience publication, Brain Facts . Several multiple choice questions followed by questions to be answered in free answer format. An answer key will be provided following the practice meet.
