^ In many ways, I think that the flexibility that comes with a full ride scholarship such as the Jefferson makes it easier to explore directions and takes risks. That’s certainly one of the advantages touted by many of the AB Duke program. The mentoring and “fast-tracking” that goes along with such programs also allows many students to find their focus more quickly.
I’m a proud and loyal Stanford grad, and my majors changed completely during the time I was at Stanford. I was extremely fortunate in that Stanford was not only my first choice, but also gave me by far the most aid, giving me freedom not to have to work. That made a huge difference. But if I were in the OP’s situation, I’d probably personally opt for the Jefferson.
You say that you are from the UK. A question I think it is important for you to ask yourself is where do you see yourself working in the future. I am an American who was at Cambridge ten years ago and I was surprised to find the British Class structure still alive and kicking in terms of both academia and society in general. Stanford (in the interests of full disclosure, I have a daughter there) or Harvard (was a Visiting Fellow there) will make you a citizen of the world and your degree will be instantly recognizable and well-regarded everywhere, whereas Virginia (an excellent school) may carry less cachet–especially across the pond.
The money end of things is such a personal calculation. We all have differing risk tolerances regarding debt. But others here have warned that journalists are poorly paid and a dying breed. Best of luck with your decision. Not a bad choice here, but each comes with different challenges. Cheers!
