do literature or combined english if thats an option for you and psychology. Psychology isn't the most respected of subjects but with hist, geog and lit it's fine. IMO I wouldn't do biology unless you will take it to A2 with psychology and do something like nursing at uni. Although there are some sciency degrees where you can get on with A2 biology and geography.
It' depends on what you want to do. If you want to do something more sciency or something such as nursing then do bio/psych/geog plus lit or history. If you want to go down the 'artsy' route then literature/history/psychology/geography.
