sexyDMD,
Please understand that I'm giving you a non-biased factual response. I was only referring to a masters in psychology in regards to how it will be perceived from a dental school admissions board.
Here's a few problems of spending 1 or 2 years pursuing graduate school in psychology:
1- AADSAS will not apply psychology courses towards your science and BCP gpa. Therefore, if your science gpa is around 3.0 or lower, then the psychology degree will not increase it what-so-ever.
2- The 1st year of all d-schools is concentrated on anatomy, biochemistry, physiology, microbiology, etc. A psychology degree will not help you prepare for any of these courses, nor does it give any indication to the d-schools of your ability to handle them.
3- The psychology courses will not help you boost your DAT score.
4- Letter of Rec from from psychology profs may mean little to d-schools.
Heck, I'm just a stranger on the internet. Did you call any d-school admissions offices and got their opinion?
If you want to get a masters in psychology for your own personal benefit and interest, than that is a completely different conversation.
