Industrial-Organizational Psychology & HR Consulting
Hi Azar, The two previous responses are quite good at providing the foundation after getting your bachelors degree in order to pursue an MD with a specialty in psychiatry. My answer will be more focused on the coursework for your bachelors program.
The first 2-3 years of course work in a pre-medicine program will be focused on physics, math, biology, chemistry (both inorganic & organic), biology and biochemistry. You will also need to take coursework in the behavioral sciences, I.e., psychology. All of this coursework is needed to obtain good scores on the Medical College Admissions Test (MCAT). While in school you will also need to develop good relationships with faculty members as you will need at least 5 strong letters of recommendation when applying to medical school. Interviews are also an important part of the selection process for admission to medical school.
I recommend going to the website for the MCAT for additional info on the requirements.
I wish you the best in your future academic studies. Linda A Robinson, Ph.D.
