Can a become neurosurgeon with BA psychology?

No, a Bachelor of Arts (BA) in Psychology is not sufficient to become a neurosurgeon. Neurosurgery is a highly specialized field of medicine that requires extensive education and training in biology, chemistry, physics, mathematics, and medicine. To become a neurosurgeon, one typically needs to complete a Bachelor of Science (BS) degree in a science-related field, followed by four years of medical school, and then at least seven additional years of residency and fellowship training.
