We haven't even spoken but I really wanted to wish you luck with your application to Cambridge. I've not been there but I did a science degree and it changed my life. Please live your dream but don't put too much pressure on yourself - Cambridge would be great but wherever you go and whatever you do, you'll do a great service to the world.
Love yourself and others and be generous, and in exchange is a small token of how I believe great students like you should have the chance to study the world. Last month I contributed a tiny sum to a Kickstarter to a powerful telescope that has an image intensifier and allows us to see distant galaxies. There is so much to know.
Mathematics is a truly beautiful subject - enjoy it and ride the wave.
Best of luck.
