I want to apply to Cambridge as well as for the Gates Cambridge scholarship. However, I am unsure of which programs I am eligible for as an American student with a 4 year bachelor of science in physics from a strong liberal arts college. I believe that in Europe, a bachelor's degree is three years. I also believe that traditionally a 1-2 year masters is completed before the PhD in most cases. The PhD program is only 3 years, and I don't know if they accept Americans directly into it from their bachelors, or if a master of some sort is required. They say regarding the PhD: "requires applicants to have followed a four-year MSci or equivalent first degree and to have achieved or be about to achieve at least an upper second class honours degree from a UK university or the equivalent." What does this mean for Americans? As far as masters degrees, there's a 12 month MPhil in Physics "by research" with some lectures as well as a thesis. There is also a 9 month MASt in Physics "taught alongside the Part III of the undergraduate MSci Physics Tripos and is designed to act as a top-up course for students who hold a 3-year undergraduate degree". Which of these do I apply for?
