After four years of medical school, you probably aren't surprised by the quality of education. I wouldn't rely on didactics. The Hippocratic oath may include teaching, but most doctors and professors are not trained to do so effectively. I definitely agree with above to read a textbook like Kaplan Saddock cover to cover, as residency will be the only time you will do such things. But I also recommend reading -- real -- books written by leaders in this field that interest you. It will not help you score higher on PRITE, but it will give you invaluable context for the knowledge that you're learning. Exposure to different perspectives and history of psychiatry will help you feel nourished, understand the "why," and can affect your practice greatly. For example, simply understanding that none of the DSM disorders are actual diseases can guide the way you learn and use that fat purple book your entire residency. Some easy and interesting reads are "Saving Normal" by Allen Frances and "Shrinks" by Lieberman.
