any PhDs?

I work in graduate school admissions - Math. This is the #1 applied Math program in the country (tied with MIT).

In my experience, everyting is important if you apply to a competitive program. GRE's, both subject and general, need to be excellent. Extremely important are rec letters.

But most importantly, the number, depth and grades you received in the classes of your subject that you took so far. If you want to study Euro History, a good application will include a transcript from a good school with lots of history classes with top grades. And letters that speak of your promise as a historian.

ETA: Even with a PhD in Math from the top school, it is difficult to find a university job. I agree with the others who said that given the time and energy one needs to put into a PhD it is not worth it unless there is really nothing else you can imagine doing. If history is your calling, then of course go for it.

I am a MD/PhD. I completed med school in about 7 years vs the normal 4 years. It is called the medical scientist program. I have a Phd in neuroscience. The program is only 3-4 years, combined with the 4 year med school program. I am currently a first year resident in neuropsychiatry, later on, perhaps I will go into more research than clinical.
There are programs like these available, if you want to go through the 7-8 year process.
good luck

My brother is finishing his second year towards a Ph.D in social psychology. He has been awarded a fellowship so he doesn't necessarily have to teach (I think he is teaching summer classes anyway) and he can spend most of his time on research. b/c it is a fellowship, the university pushes him to complete it in 5 years (trying to get their money's worth??) he already had his masters degree.
I guess it depends on the program, I heard it can take 5-8 years. (he is at Rutgers)

thanks for all the advice!!

I tought Euro History on the HS level...and Psych on the college level...and I think the only way to make the switch is to get a PhD (as a MA in history wouldn't get me the job I want)...

also...I would really love to study more just for my own knowledge...and eventually write books...or historical screenplays...
