In the DC universe Dr.Harleen Quinzel is described as a 'trained psychiatrist', however she is not, because in the US to become a psychiatrist you must first obtain a bachelor's degree- 4 years, then medical school- 4 years and then a residency- 3-7 years. She was born in 1990 (suicide squad) meaning she was 25 when the film was released. To be a psychiatrist, that could work with the Joker as portrayed, she would be 29 at least. She is described as having a genius level IQ, but she graduated at the standard time. (In other unreliable sources, it is said that she has a PhD in psychiatry, which is not a direct route to becoming a psychiatrist and would add another 3 years on top of what is already described, the doctor title is obtained through a M.D. or an O.D. Correct to US, she attended Gotham State University, also Gotham is not a state.) I love the DC universe, but I was just curious. (Also want to be a psychiatrist.)
