Before I start, here's a summary of who I am. I'm a fourteen year old, living in Ireland, with a love of physics, maths and anything else of that nature. I dream of one day working for a big research company, and discovering amazing things that will shock the entire world. But, before I can do that, I need someone to bring me back down to Earth and tell me about what I can do with physics degree. And what I have to do to get that physics degree in the first place. So here are my 3 questions: What subjects do I need to get 100% in, in order to assure my spot in a university? What am I going to be doing in university? What can I then do with my physics degree? Thanks in advance for all your help. It's much appreciated.
