A psychologist is a professional who evaluates and studies behavior and mental processes
Thart's cool. I'm watching a psychologist speak right now. Tell me more.
To become one you need a university degree in psychology or  a behavioral course so as to get the skill to can also evaluate, diagnose, treat, and study mental processes.
That is true. I have taken general psychology and enjoyed it. I like to play chess too! A mental sport.
You can either be an applied psychologist  and become a  "practitioner or research-orientated psychologist which involve scholastic work
Tha'ts true. I enjoy psycho anayltically minded people. Do you know Freud?
Endorsement is done by American Psychological Association (APA)  and require that applied psychologists be trained as both researchers and practitioners
I think that association is great, not always 100% right of course.
