Hi,
I know choosing your GCSE's can prove difficult at times, especially as doing so can restrict your choice at A-Level. I too found it difficult to decide.
It's great that you know what you want to do with your life, career wise. That will give you some indication of what subjects you should choose.
ICT was compulsory in my school, therefore I didn't have a say in it. I did geography too.
You're thinking about doing very strong, academic subjects, which will open many doors for you at A-Level; geography being one of them, as it is a 'traditional' subject, which are 'generally' favoured by universities (not all Universities, you'd need to contact your University of choice and get more information on this)
ICT is a soft subject, however it relates more to your desired career path than geography. It all depends on what you want to do at A-Level.
University of Cambridge for example require specific subjects, such as Maths and Physics at A-Level, and would like you to have a third subject in a science/maths/technology subject, which I assume includes ICT.
As you're already considering strong GCSE's, my advice is to go with ICT (Or technology for that matter) - I enjoyed both Geography and ICT, so either way, you should be happy.
Hope this helps.
