If you're not interested in going to medical school, what can you do with a B.A. in Psychology?
Become a Behavior Analyst. Look into the psychology of Applied Behavior Analysis. There is a credential for B.A. psychology called BCABA (Board Certified Associate Behavior Analyst). Also, there is the credential for M.A. psychology called BCBA (Board Certified Behavior Analyst).

Teach kids or adults with autism, PDD, ADHD, OCD. You don't need a graduate psychology or education degree to do that. Just need to be working on your B.A. psychology, education, or other therapy degree.
The field to get started in as an undergrad is called Applied Behavior Analysis. This is based on your basic Pavlovian & Skinnerian psychological theories of behavior modification.
In Applied Behavior Analysis (ABA), you can learn how to do psychological testing & intakes, work with therapists & other psychologists/psychiatrists, learn how to do teaching & behavior modification & behavior therapy, learn how to manage clients' cases, and learn how to interact with clients & their family members. You can do all this in Applied Behavior Analysis before even graduating from college with a B.A. psychology degree.
You can do this part-time as an undergrad. And if you like it, there are full-time postions & ABA classes (BCABA certification) after you graduate. There are even master's-level programs in Applied Behavior Analysis (BCBA certification) that overlap with School Psychology, Marriage Therapy, & Family Therapy.
Later, if you find out that Applied Behavior Analysis is for you... there are many people with Autism, PDD, ADHD, OCD, & other behavior problems that need help through behavior modification & behavior therapy. If you find out that Applied Behavior Analysis is not for you, then at least you were able to get lots of clinical psychological exeperience as and undergraduate psychology major and use that information when applying to other graduate psychology degrees.
