No both the universities have only mentioned that I'm accepted as a full-time student for the MPH in Epidemiology program, there arent any locks in terms of time frame.Glad to be of assistance! I see that you're in a tough spot. I actually have a quick question for you since you mentioned that the programs' durations vary. In your acceptance letter, did both universities tell you which program you were admitted to, and therefore locks you into a particular time frame? For example, I was accepted into the MPH program at JHU, which is 11 months long. I hope this makes sense. There's probably a more eloquent way to phrase this lol.
Regarding your questions, people are ambivalent about rankings. Some say it's a huge factor for employers because they can see which school you went to right away on your CV/resume. Others say employers aren't that superficial and do not weigh rankings that much. This point happens to tie in with your third question. My opinion is that if you know you can succeed in an elite program, you can't lose later on. As for the availability of TA positions, that is a question that you need to ask the Dean of Admissions or MPH students currently attending those universities. I imagine that there is a large flux in TA positions at every institution and you will not know exactly how many available spots there are.
Hope this helps!
- Both the colleges require different credits to complete the degree. Should that be taken into consideration?
