How to improve my application

as well as making me seem more well-rounded?

Hello,

I have just started Sixth Form with the following subjects: Maths, Further Maths, Economics and Computer Science. I would like to study Computer Science at Cambridge.

I already have a fairly strong academic profile (9A* 2A at GCSE), and I believe I will be able to work hard enough to achieve at least A*A*AA at A-Level.

However, I would like to improve my application in other areas by entering competitions, making my own projects, doing work experience, community service, etc.

These are all things I believe I would enjoy doing, so aren't just to improve my application, but would hopefully do that as well.

I was wondering if anyone had any tips on how I could improve my overall application by giving me some impressive things to reference on my personal statement and discuss in my interview, as well as making me seem more well-rounded?

Do you know any specific competitions I should enter? Or any steps I should take? Preferably related to Computer Science, but please let me know if you have anything else you think may help.

I have also been considering teaching myself Python and/or C# - would that help?

Thanks.
