I am at the end of my AS year at college, so I need to be thinking about uni choices. I will have to get my application for cambridge in in october. I am stuck between taking Maths or Physics. I really enjoy both, and would ideally like to take both to degree level, as I find them both really interesting. Some universities do a "maths + physics" course, but I don't want to end up as a "jack of all trades" and be able to get a PhD in neither subject... Any advice?
