As a college psychology instructor, I thought this background on MCAT Psych/Soc might give you some deeper inspiration for studying these subjects. Best of luck to all of you!
Students often wonder why they need to study psychology and sociology in order to study medicine. Even more frequently, in my experience, they wonder why the MCAT specifically tests their knowledge of these two social sciences. Even if they are not psychiatrists, all physicians need a basic understanding of human behavior, as patients could present with psychological symptoms and conditions in any setting. That's how psychology helps medical professionals. Sociology assists doctors by helping them to become culturally competent, while learning how society impacts a patient's health. Although I am a social scientist by training, I am also a clinician, and I can attest that a health professional's familiarity with sociological and psychological (even if they are non-clinical) concepts makes a huge difference.
The MCAT psych/soc is the final section of the exam. Despite its place in the order of the test, you are preparing for success as a physician early by studying this material. Mastering this critical content will help you to succeed in medical school and as a physician. Psych/Soc questions do not just test for mere understanding; rather, the questions ask you to apply the concepts you've learned. This type of application of learning is similar to what one would do as an actual medical student or doctor.
