Is medical school admission squashing creativity?

Those who come to discover the beauty of medicine through another path, later in their academic trajectories, find themselves significantly behind—with the gap so large that many are discouraged to try. It's too late to become a doctor, they think. And the mandates keep escalating. In 2015, for example, aspiring medical students will have to endure a new MCAT (Medical College Admission Test): about two hours longer, with new sections on psychology, sociology, and ethics in addition to the previous sections testing physics, chemistry, biology, verbal reasoning, and writing. I could imagine a situation where actually grappling with ethical situations in real life could keep someone from adequately preparing for the ethical section of the exam.
