Maths, Further Maths, Chemistry, Physics.
I am expecting that I'll study for a maths intensive degree and these seemed like the most sensible options considering my interests and career ambitions. In choosing sciences and maths, I get to (more or less) stay away from coursework and essay writing which is a relief.
Maths is awesome. I love patterns and maths is essentially playing with abstract patterns and relationships. Recently, I've become interested in coding and so the stats knowledge from that is something I want to try out and perhaps take further - chess and poker analysis, machine learning, artificial intelligence, biostatics, finance... lots of cool applications.
Chemistry and Physics are awesome because in studying them you develop a hard understanding and therefore utility of the world around you. Of the sciences, they seem vastly the most interesting. I'm not looking forward to physics because the lecturer doesn't have a great reputation but chemistry seems super fun!
