I did a semester of post bacc cause I wanted to get back into the swing of school after a layoff. I also wanted to learn business cause as a scientist I didn't know squat about budgets, finances, or administration.
Then someone talked me into a MPH program. I stacked up my classes and went to town on the program. I got my MPH in a year. Now I have a lot of knowledge in public health, administration, finances, medicare/medicaid, health systems, epidemiology, biostatistics, and health care managment.
One of the greatest things I have decided.
Now, I am finishing up an internship (which lets me post here on SDN) and I learn more cause of the hands on experience. Like yesterday I was working in a local health department with family planning clinic and STD testing. I really didn't know all the services and problems with our society until you go and look at it first hand.
Did it help with medical school apps? In my opinion hell yeah...not so much for the paper aspect but I was able to talk for great length in my interviews about multiple health related issues and had some great conversations.
