Hi, I don't want to bore you with the story of my life but basically I am 18, I have no grades. The reason for that is because I had cancer at 16. I was offered to go back to school but I naively turned it down. Now I am a milkman. I started 3 months ago. I have become increasingly anxious about my future, its almost as though I am having a mid-life crisis, or rather, a early-life crisis. The reason is I want to be a scientist in physics. I am fascinated by how to universe works and want to be a part of our evolution to find out the wonders of the universe. Am I too late to go to collage and get my maths and other stuff, then go to uni? Also what would I need to study, apart from A-level Maths and physics?
