Hi all. I am 23, in my first year of an MPH. I took a year off after college before coming back. While in college, I applied to PhD programs, but didn't get into any. The feedback was that it was hard to get in without a master's and I didn't have enough experience. Now I'm worried that I lost my shot at a PhD, because I'd be 25 by the time I started, which is on the later side for starting a PhD. What do you guys think? Should I give up on it or would it be plausible?
