Greetings Physics Forum and its members, My name's Ash, I'm a nineteen year old A-Level student in the UK, I think the US-equivalent of A-levels are AP's? Although I'm not sure. I'm currently studying Physics, Maths, Chemistry & Psychology, with the hope of going onto a Physics degree at university later on. Anyway, I've been lurking for a while and I just thought I'd introduce myself. So, hello!
