Hi Eddwharton
As a general rule, economics is considered better than geography. However say you wanted to do Geography at uni, then Geography is quite an important subject to do! It's suggested to talk to your teachers, ask advice - if you know what you want to do then fit your subjects around it.. If you don't know yet, then choose the most intellectual ones..
However these are all good courses and if you do well there should be no problem with any of these courses.
