Dr. Ray’s Answer
I went to school so long ago (I graduated with my Ph.D. in 1972) that my experiences are probably out of date. If you decide to major in psychology the department will have a list of required courses, plus suggested electives. In my opinion some background in statistics and biology is helpful. I also suggest you take some literature courses that require writing; there is a lot of good psychology in well written novels, plus many employers today want employees who can write and express themselves well.
I recommend you look at the web sites of some colleges in your area and see what the requirements are for a major in psychology. Most colleges are happy to talk to prospective students.
Good luck with your career pursuits.
